Commercial salmon season is shut down — again. Will California’s iconic fish ever recover?

Tuesday, April 15, 2025

In summary While it’s an unprecedented third year in a row for no commercially caught salmon, brief windows will be allowed for sportsfishing in California. Facing the continued collapse of Chinook salmon, officials today shut down California’s commercial salmon fishing season for an unprecedented third year in a row.  Under the decision by an interstate fisheries agency, recreational salmon fishing will be allowed in California for only brief windows of time this spring. This will be the first year that any sportfishing of Chinook has been allowed since 2022. Today’s decision by the Pacific Fishery Management Council means that no salmon caught off California can be sold to retail consumers and restaurants for at least another year. In Oregon and Washington, commercial salmon fishing will remain open, although limited. “From a salmon standpoint, it’s an environmental disaster. For the fishing industry, it’s a human tragedy, and it’s also an economic disaster,” said Scott Artis, executive director of the Golden State Salmon Association, an industry organization that has lobbied for river restoration and improved hatchery programs.  The decline of California’s salmon follows decades of deteriorating conditions in the waterways where the fish spawn each year, including the Sacramento and Klamath rivers. California’s salmon are an ecological icon and a valued source of food for Native American tribes. The shutdown also has an economic toll: It has already put hundreds of commercial fishers and sportfishing boat operators out of work and affected thousands of people in communities and industries reliant on processing, selling and serving locally caught salmon.  California’s commercial fishery has never been closed for three years in a row before.  Some experts fear the conditions in California have been so poor for so long that Chinook may never rebound to fishable levels. Others remain hopeful for major recovery if the amounts of water diverted to farms and cities are reduced and wetlands kept dry by flood-control levees are restored.  This year’s recreational season includes several brief windows for fishing, including a weekend in June and another in July, or a quota of 7,000 fish.   Jared Davis, owner and operator of the Salty Lady in Sausalito, one of dozens of party boats that take paying customers fishing, thinks it’s likely that this quota will be met on the first open weekend for recreational fishing, scheduled for June 7-8.   “Obviously, the pressure is going to be intense, so everybody and their mother is going to be out on the water on those days,” he said. “When they hit that quota, it’s done.” One member of the fishery council, Corey Ridings, voted against the proposed regulations after saying she was concerned that the first weekend would overshoot the 7,000-fish quota. Davis said such a miniscule recreational season won’t help boat owners like him recover from past closures, though it will carry symbolic meaning. “It might give California anglers a glimmer of hope and keep them from selling all their rods and buying golf clubs,” he said.  “It continues to be devastating.

Fewer returning salmon

This pig’s bacon was delicious. But she’s alive and well

A company called Mission Barns is cultivating pork fat in bioreactors and turning it into meatballs and other products. Honestly, they're pretty darn good.

I’m eating Dawn the Yorkshire pig and she’s quite tasty. But don’t worry. She’s doing perfectly fine, traipsing around a sanctuary in upstate New York. (Word is that she appreciates belly rubs and sunshine.) I’m in San Francisco, at an Italian joint just south of Golden Gate Park, enjoying meatballs and bacon not made of meat in the traditional sense, but of plants mixed with “cultivated” pork fat. Dawn, you see, donated a small sample of fat, which a company called Mission Barns got to proliferate in devices called bioreactors by providing nutrients like carbohydrates, amino acids, and vitamins — essentially replicating the conditions in her body. Because so much of the flavor of pork and other meats comes from the animal’s fat, Mission Barns can create products like sausages and salami with plants, but make them taste darn near like sausages and salami. I’ve been struggling to describe the experience, because cultivated meat short-circuits my brain — my mouth thinks I’m eating a real pork meatball, but my brain knows that it’s fundamentally different, and that Dawn (that’s her above) didn’t have to die for it. This is the best I’ve come up with: It’s Diet Meat. Just as Diet Coke is an approximation of the real thing, so too are cultivated meatballs. They simply taste a bit less meaty, at least to my tongue. Which is understandable, as the only animal product in this food is the bioreactor-grown fat.Cultivated pork is the newest entrant in the effort to rethink meat. For years, plant-based offerings have been mimicking burgers, chicken, and fish with ever-more convincing blends of proteins and fats. Mission Barns is one of a handful of startups taking the next step: growing real animal fat outside the animal, then marrying it with plants to create hybrids that look, cook, and taste more like what consumers have always eaten, easing the environmental and ethical costs of industrial livestock. The company says it’s starting with pork because it’s a large market and products like bacon are fat-rich, but its technology is “cell-agnostic,” meaning it could create beef and chicken, too. Matt Simon Honestly, Mission Barns’ creations taste great, in part because they’re “unstructured,” in the parlance of the industry. A pork loin is a complicated tangle of fat, muscle cells, and connective tissues that is very difficult — and expensive — to replicate, but a meatball, salami, or sausage incorporates other ingredients. That allows Mission Barns to experiment with what plant to use as a base, to which they add spices to accentuate the flavors. It’s a technology that they can iterate, basically, crafting ever-better meats by toying with ingredients in different ratios. So the bacon I ate, for instance, had a nice applewood smoke to it. The meatballs had the springiness you’d expect. During a later visit to Mission Barns’ headquarters across town, I got to try two prototypes of its salami as well — both were spiced like you’d expect, but less elastic, so they chewed a bit more easily than what you’d find on a charcuterie board. (The sensation of food in the mouth is known in the industry as “mouthfeel,” and nailing it is essential to the success of alt-meats.) The salami slices even left grease stains on the paper they were served on — Dawn’s own little mark on the world. Matt Simon I was one of the first people to purchase a cultivated pork product. While Mission Barns has so far only sold its products at that Italian restaurant and, for a limited time, at a grocery store in Berkeley — $13.99 for a pack of eight meatballs, similar to higher-end products from organic and regenerative farms — it is fixing to scale up production and sell the technology to other companies to produce more cultivated foods. (It is assessing how big the bioreactors will have to be to reach price parity with traditional meat products.) The idea is to provide an alternative to animal agriculture, which uses a whole lot of land, water, and energy to raise creatures and ship their flesh around the world. Livestock are responsible for between 10 and 20 percent of humanity’s greenhouse gas emissions — depending on who’s estimating it — and that’s to say nothing of the cruelty involved in keeping pigs and chickens and cows in unsavory, occasionally inhumane, conditions.Getting animal cells to grow outside of an animal, though, ain’t easy. For one, if cells don’t have anything to attach to, they die. So Mission Barns’ cultivator uses a sponge-like structure, full of nooks and crannies that provides lots of surface area for the cells to grow. “We have our media, which is just the nutrient solution that we give to these cells,” said Saam Shahrokhi, chief technology officer at Mission Barns. “We’re essentially recapitulating all of the environmental cues that make cells inside the body grow fat, [but] outside the body.” While Dawn’s fat is that of a Yorkshire pig, Shahrokhi said they could easily produce fat from other breeds like the Mangalitsa, known as the Kobe beef of pork. (In June, the company won approval from the U.S. Department of Agriculture to bring its cultivated fat to market.)Fat in hand, Mission Barns can mix it with plant proteins. If you’re familiar with Impossible Foods, it uses soy to replicate the feel and look of ground beef and adds soy leghemoglobin, which is similar to the heme that gives meat its meaty flavor. Depending on the flavor and texture it’s trying to copy, Mission Bay uses pea protein for the meatballs and sausages, wheat for the bacon, and fava beans for the salami. “The plant-based meat industry has done pretty well with texture,” said Bianca Le, head of special projects at Mission Barns. “I think what they’re really missing is flavor and juiciness, which obviously is where the fat comes in.” Matt Simon But the fat is just the beginning. Mission Barn’s offerings not only have to taste good, but also can’t have an offputting smell when they’re coming out of the package and when they’re cooking. The designers have to dial in the pH, which could degrade the proteins if not balanced. How the products behave on the stove or in the oven has to be familiar, too. “If someone has to relearn how to cook a piece of bacon or a meatball, then it’s never going to work,” said Zach Tyndall, the product development and culinary manager at Mission Barns.When I pick up that piece of salami, it has to feel like the real thing, in more ways than one. Indeed, it’s greasy in the hand and has that tang of cured meat. It’s even been through a dry-aging process to reduce its moisture. “We treat this like we would a conventional piece of salami,” Tyndall said. Cultivated meat companies may also go more unconventional. “I also love the idea of taking their pork fat and putting it in a beef burger — what would happen if you did that?” said Barb Stuckey, chief new product strategy officer at Mattson, a food developer that has worked with many cultivated meat companies. “Mixing species, it’s not something we typically do. But with this technology, we can.” Of course, in this new frontier of food, the big question is: Who exactly is this for? Would a vegetarian or vegan eat cultured pork fat if it’s divorced from the cruelty of factory farming? Would meat-eaters be willing to give up the real thing for a facsimile? Mission Barns’ market research, Le said, found that its early adopters are actually flexitarians — people who eat mostly plant-based but partake in the occasional animal product. But Le adds that their first limited sale to the public in Berkeley included some people who called themselves vegetarians and vegans.  Mission Barns There’s also the matter of quantifying how much of an environmental improvement cultivated fat might offer over industrial pork production. If scaled up, one benefit of cultivated food might be that companies can produce the stuff in more places — that is, instead of sprawling pig farms and slaughterhouses being relegated to rural areas, bioreactors could be run in cities, cutting down on the costs and emissions associated with shipping. Still, those factories would need energy to grow fat cells, though they could be run on renewable electricity. “We modeled our process at the large commercial scale, and then compared it to U.S. bacon production,” Le said. (The company would not offer specific details, saying it is in the process of patenting its technique.) “And we found that with renewable energy, we do significantly better in terms of greenhouse gas emissions.”Whether or not consumers bite, though, remains to be seen. The market for meat alternatives in the U.S. has majorly softened of late: Beyond Meat, which makes plant-based products like burgers and sausages, has seen revenues drop significantly, in part because of consumers’ turn away from processed foods. But by licensing its technology elsewhere, Mission Barns’ strategy is to break into new markets beyond the U.S.The challenges of cultivated meat go beyond the engineering once you get to the messaging and branding — telegraphing to consumers that they’re buying something that may in fact be partially meat. “When you buy chicken, you get 100 percent chicken,” Stuckey said. “I think a lot of people go into cultivated meat thinking what’s going to come onto the market is 100 percent cultivated chicken, and it’s not going to be that. It’s going to be something else.” Regardless of the trajectory of cultivated fat products, Dawn will continue mingling with llamas, soaking up the sunshine, and getting belly rubs in upstate New York — even as she makes plants taste more like pork.  This story was originally published by Grist with the headline This pig’s bacon was delicious.

Agriculture Linked To Melanoma Cluster In Pennsylvania

By Dennis Thompson HealthDay ReporterTUESDAY, Nov. 18, 2025 (HealthDay News) — A melanoma cluster found in the heart of Pennsylvania farm country has highlighted potential links between agriculture and skin cancer.Adults 50 and older living in a 15-county stretch of south-central Pennsylvania were 57% more likely to develop melanoma than people living elsewhere in the state, researchers reported Nov. 14 in the journal JCO Clinical Cancer Informatics.The risk wasn’t limited to farm workers who spend their days toiling in the sun, either. Risk was higher in both rural and metropolitan areas located near active farmland, and the risk remained even after researchers accounted for residents’ exposure to ultraviolet radiation.“Melanoma is often associated with beaches and sunbathing, but our findings suggest that agricultural environments may also play a role,” researcher Dr. Charlene Lam, an associate professor of dermatology at Penn State Health across several locations in central Pennsylvania, said in a news release.“And this isn’t just about farmers. Entire communities living near agriculture, people who never set foot in a field, may still be at risk,” Lam said.For the study, researchers analyzed five years of cancer registry data from 2017 through 2021 in Pennsylvania.They found that counties in the melanoma clusters had more cultivated farmland — an average of 20% versus 7% for non-cluster counties.For every 10% in the amount of cultivated land in a region, melanoma cases rose by 14%, results show.Melanoma also coincided with more use of herbicides, researchers said, with an average 17% of herbicide-treated land in cluster counties versus less than 7% in non-cluster counties.Every 9% increase in herbicide use corresponded to a 14% increase in melanoma cases, researchers said."Pesticides and herbicides are designed to alter biological systems,” senior researcher Eugene Lengerich, a professor of public health sciences at Penn State in State College, Pennsylvania said in a news release. “Some of those same mechanisms, like increasing photosensitivity or causing oxidative stress, could theoretically contribute to melanoma development.”Previous studies have found that pesticides and herbicides heighten sensitivity to sunlight, disrupt immune function and damage DNA in animals and plants — all of which might increase melanoma risk in humans, researchers noted.The researchers noted that the risk isn’t limited to farm workers applying herbicides to a field. These chemicals can drift through the air, settle in household dust and seep into water supplies.“Our findings suggest that melanoma risk could extend beyond occupational settings to entire communities,” Lam said. “This is relevant for people living near farmland. You don’t have to be a farmer to face environmental exposure.”Similar patterns have been found in agricultural regions in Utah, Poland and Italy, researchers noted.However, researchers noted that the new study doesn’t prove a cause-and-effect link between agriculture and melanoma, but only shows an association."Think of this as a signal, not a verdict,” lead researcher Benjamin Marks, a medical student at the Penn State College of Medicine in Pittsburgh, said in a news release.“The data suggest that areas with more cultivated land and herbicide use tend to have higher melanoma rates, but many other factors could be at play like genetics, behavior or access to health care,” Marks said. “Understanding these patterns helps us protect not just farmers, but entire communities living near farmland.”In the meantime, people who live near agricultural areas should protect themselves from melanoma by performing regular skin checks, slopping on sunscreen, and slipping on hats and clothing to protect against sun exposure, Lengerich said.SOURCES: Penn State, news release, Nov. 14, 2025; JCO Clinical Cancer Informatics, Nov. 14, 2025Copyright © 2025 HealthDay.

With neonicotinoid pesticide ban, France’s birds make a tentative recovery - study

Analysis shows small hike in populations of insect-eating species after 2018 ruling, but full recovery may take decadesInsect-eating bird populations in France appear to be making a tentative recovery after a ban on bee-harming pesticides, according to the first study to examine how wildlife is returning in Europe.Neonicotinoids are the world’s most common class of insecticides, widely used in agriculture and for flea control in pets. By 2022, four years after the European Union banned neonicotinoid use in fields, researchers observed that France’s population of insect-eating birds had increased by 2%-3%. These included blackbirds, blackcaps and chaffinches, which feed on insects as adults and as chicks. Continue reading...

Insect-eating bird populations in France appear to be making a tentative recovery after a ban on bee-harming pesticides, according to the first study to examine how wildlife is returning in Europe.Neonicotinoids are the world’s most common class of insecticides, widely used in agriculture and for flea control in pets. By 2022, four years after the European Union banned neonicotinoid use in fields, researchers observed that France’s population of insect-eating birds had increased by 2%-3%. These included blackbirds, blackcaps and chaffinches, which feed on insects as adults and as chicks.The results could be mirrored across the EU, where the neonicotinoid ban came into effect in late 2018, but research has not yet been done elsewhere. The lead researcher, Thomas Perrot from the Fondation pour la recherche sur la biodiversité in Paris, said: “Even a few percentage [points’] increase is meaningful – it shows the ban made a difference. Our results clearly point to neonicotinoid bans as an effective conservation measure for insectivorous birds.”Like the EU, the UK banned neonicotinoids for outdoor general use in 2018, although they can be used in exceptional circumstances. They are still widely used in the US, which has lost almost 3 billion insectivorous birds since the 1970s.The study, which was published in the journal Environmental Pollution, looked at data from more than 1,900 sites across France collected by skilled volunteer ornithologists for the French Breeding Bird Survey. They divided the data into two groups – the five years before the ban, from 2013 to 2018; and the post-ban period from 2019 to 2022.Perrot’s team analysed data on 57 bird species at these sites, each of which measured 2km by 2km (1.25 miles). They found that the numbers of insectivorous birds at pesticide-treated sites were 12% lower compared with sites where there was no neonicotinoid use.It is likely that other insect-eating animals such as small mammals, bats and even fish could also be seeing the benefits, Perrot said. Generalist birds such as the wood pigeon and house sparrow appeared to be less affected, probably because they have more flexible diets and do not rely on insects.Frans van Alebeek, policy officer for rural areas at BirdLife Netherlands, said: “A lot of pressure was necessary to force governments to make this ban. There was huge pressure on the EU parliament from citizens.“I was surprised you could already see recovery,” said Alebeek, who was not involved in the research. “It’s extremely difficult to study this – which makes this study so special. The positive message is that it helps to ban pesticides and it will result in the recovery of wildlife.”Other researchers were more cautious about the findings. James Pearce-Higgins, director of science at the British Trust for Ornithology, said: “It’s a study that shows there may be early signs of weak population recovery but the results are uncertain and could be down to other correlated factors.”Habitat and climate are other factors that could explain variations in bird numbers, but it is difficult to be definitive. “This study highlights the value of long-term monitoring so we can better understand these trends in the future,” Pearce-Higgins said.Bird numbers have fallen sharply in many countries around the world, and several studies indicate that the loss of insects is driving declines.A farmer spraying insecticides in a field. Photograph: Arterra Picture Library/AlamyNeonicotinoids are systemic insecticides, which are absorbed by plants and become present throughout their tissues, making any part of the plant toxic to insects that feed on it. They were introduced in the 1990s and quickly became widespread across Europe.Mass die-offs of bees were first reported in the early 2000s in France and Germany. Research showed these chemicals – even in tiny doses – could affect bees’ navigation and foraging. By the 2010s their impact on bees had become a big public issue, and by 2018 the EU banned them for almost all outdoor use, despite fierce pushback from agribusiness, especially chemical companies.“The weak recovery after the ban makes sense,” said Perrot. “Neonicotinoids persist in soils for years and can keep affecting insects.“Overall, our results suggest that it will take several decades for insectivorous bird populations to recover. But we think that’s normal, because studies on other pesticides like DDT show that most bird populations take 10 to 25 years to fully recover.”Pesticides are having a significant impact on birds in developing countries, where there are fewer restrictions and the effects remain largely undocumented.Birds are strongly affected by farming, including pesticide use and habitat loss. Perrot said more sustainable farming, which reduced pesticides and restored semi-natural habitats, would help bird populations recover. Some EU policies already encourage this through “green infrastructure” funding. “But if agriculture keeps focusing on maximum yields instead of sustainability, we’ll keep seeing the same declines,” Perrot said.Alebeek said: “Neonicotinoids are part of a trend in which industry is getting better and better at finding chemicals that are extremely effective at low concentrations – you use less but the toxicity is not going down.“To me, it shows that our system of testing pesticides before they are allowed on the market is not good enough. We have done it for 50 years for all kinds of pesticides – we go through the same process every 10 years and learn very little from history.”Find more age of extinction coverage here, and follow the biodiversity reporters Phoebe Weston and Patrick Greenfield in the Guardian app for more nature coverage

Returning farming to city centers

4.182 (Resilient Urbanism: Green Commons in the City), a new subject funded by the MIT Human Insight Collaborative (MITHIC), teaches students about sustainable agriculture in urban areas.

A new class is giving MIT students the opportunity to examine the historical and practical considerations of urban farming while developing a real-world understanding of its value by working alongside a local farm’s community.Course 4.182 (Resilient Urbanism: Green Commons in the City) is taught in two sections by instructors in the Program in Science, Technology, and Society and the School of Architecture and Planning, in collaboration with The Common Good Co-op in Dorchester.The first section was completed in spring 2025 and the second section is scheduled for spring 2026. The course is taught by STS professor Kate Brown, visiting lecturer Justin Brazier MArch ’24, and Kafi Dixon, lead farmer and executive director of The Common Good.“This project is a way for students to investigate the real political, financial, and socio-ecological phenomena that can help or hinder an urban farm’s success,” says Brown, the Thomas M. Siebel Distinguished Professor in History of Science. Brown teaches environmental history, the history of food production, and the history of plants and people. She describes a history of urban farming that centered sustainable practices, financial investment and stability, and lasting connections among participants. Brown says urban farms have sustained cities for decades.“Cities are great places to grow produce,” Brown asserts. “City dwellers produce lots of compostable materials.”Brazier’s research ranges from affordable housing to urban agricultural gardens, exploring topics like sustainable architecture, housing, and food security.“My work designing vacant lots as community gardens offered a link between Kafi’s work with Common Good and my interests in urban design,” Brazier says. “Urban farms offer opportunities to eliminate food deserts in underserved areas while also empowering historically marginalized communities.”Before they agreed to collaborate on the course, Dixon reached out to Brown asking for help with several challenges related to her urban farm including zoning, location, and infrastructure.“As the lead farmer and executive director of Common Good Co-op, I happened upon Kate Brown’s research and work and saw that it aligned with our cooperative model’s intentions,” Dixon says. “I reached out to Kate, and she replied, which humbled and excited me.” “Design itself is a form of communication,” Dixon adds, describing the collaborative nature of farming sustenance and development. “For many under-resourced communities, innovating requires a research-based approach.”The project is among the inaugural cohort of initiatives to receive support from the SHASS Education Innovation Fund, which is administered by the MIT Human Insight Collaborative (MITHIC).Community development, investment, and collaborationThe class’s first section paired students with community members and the City of Boston to change the farm’s zoning status and create a green space for long-term farming and community use. Students spent time at Common Good during the course, including one weekend during which they helped with weeding the garden beds for spring planting.One objective of the class is to help Common Good avoid potential pitfalls associated with gentrification. “A study in Philadelphia showed that gentrification occurs within 1,000 feet of a community garden,” Brown says. “Farms and gardens are a key part of community and public health,” Dixon continues. Students in the second section will design and build infrastructure — including a mobile chicken coop and a pavilion to protect farmers from the elements — for Common Good. The course also aims to secure a green space designation for the farm and ensure it remains an accessible community space. “We want to prevent developers from acquiring the land and displacing the community,” Brown says, avoiding past scenarios in which governments seized inhabitants’ property while offering little or no compensation.Students in the 2025 course also produced a guide on how to navigate the complex rules surrounding zoning and related development. Students in the next STS section will research the history of food sovereignty and Black feminist movements in Dorchester and Roxbury. Using that research, they will construct an exhibit focused on community activism for incorporation into the coop’s facade.Imani Bailey, a second-year master’s student in the Department of Architecture’s MArch program, was among the students in the course’s first section.“By taking this course, I felt empowered to directly engage with the community in a way no other class I have taken so far has afforded me the ability to,” she says.Bailey argues for urban farms’ value as both a financial investment and space for communal interaction, offering opportunities for engagement and the implementation of sustainable practices. “Urban farms are important in the same way a neighbor is,” she adds. “You may not necessarily need them to own your home, but a good one makes your property more valuable, sometimes financially, but most importantly in ways that cannot be assigned a monetary value.”The intersection of agriculture, community, and technologyTechnology, the course’s participants believe, can offer solutions to some of the challenges related to ensuring urban farms’ viability. “Cities like Amsterdam are redesigning themselves to improve walkability, increase the appearance of small gardens in the city, and increase green space,” Brown says. By creating spaces that center community and a collective approach to farming, it’s possible to reduce both greenhouse emissions and impacts related to climate change.Additionally, engineers, scientists, and others can partner with communities to develop solutions to transportation and public health challenges. By redesigning sewer systems, empowering microbiologists to design microbial inoculants that can break down urban food waste at the neighborhood level, and centering agriculture-related transportation in the places being served, it’s possible to sustain community support and related infrastructure.“Community is cultivated, nurtured, and grown from prolonged interaction, sharing ideas, and the creation of place through a shared sense of ownership,” Bailey argues. “Urban farms present the conditions for communities to develop.” Bailey values the course because it leaves the theoretical behind, instead focusing on practical solutions. “We seldom see our design ideas become tangible," she says. “This class offered an opportunity to design and build for a real client in the real world.”Brazier says the course and its projects prove everyone has something to contribute and can have a voice in what happens with their neighborhoods. “Despite these communities’ distrust of some politicians, we partnered to work on solutions related to zoning,” he says, “and supported community members’ advocacy efforts.”

Red Tractor ad banned for misleading environmental claims

The Advertising Standards Authority upheld a complaint by environment charity River Action.

Red Tractor ad banned for misleading environmental claimsRed TractorThe Red Tractor advert was last shown in 2023 but will now be banned for future use unless it is updatedA TV advert by Red Tractor, the UK's biggest certifier of farm products on supermarket shelves, has been banned for exaggerating the scheme's environmental benefits and misleading the public.The Advertising Standards Authority (ASA) ruled the organisation had provided "insufficient evidence" that its farms complied with basic environmental laws to substantiate the claims in its ad.Environmental group River Action, which brought the complaint in 2023, said the ruling showed the scheme was "greenwashing" and urged supermarkets to stop using it.But Red Tractor called the watchdog's decision "fundamentally flawed" and argued that the scheme's focus was animal welfare not environmental standards.In 2021, Red Tractor aired an advert in which it said: "From field to store all our standards are met. When the Red Tractor's there, your food's farmed with care."You can watch it below.Watch: the ad banned by the Advertising Standards AuthorityThe environmental charity River Action took issue with the ad, which ran for a further two years, and complained to the watchdog that it suggested to consumers that Red Tractor farms will "ensure a high degree of environmental protection".The charity pointed to a report by the Environment Agency, released in 2020, which looked at how many breaches of environmental law there were on Red Tractor farms in the previous five years. The report concluded that these farms were "not currently an indicator of good environmental performance".After more than two years of investigation - one of the longest running - the Advertising Standards Authority (ASA) upheld the complaint.It said that Red Tractor had failed to provide "sufficient evidence" that its farms met "basic" environmental laws and had a good environmental outcome to substantiate the claims in the ad.It also ruled that as a result the advert was "misleading" and "exaggerated" the benefits of the scheme.River Action welcomed the decision by the ASA and called on supermarkets to act."What this shows is that for their environmental credentials Red Tractor has been misleading the public and their supplies," said Amy Fairman, head of campaigns at River Action. "So, we're looking for suppliers like supermarkets to really examine and take stock of what is on their shelves."She added that challenging such adverts was important because of the pollution risk to the environment from agricultural pollution.In 2022, the Environment Audit Committee concluded that agriculture was one of the most common factors preventing rivers from being in good health - affecting 40% of them. The risks to the environment include from slurry and pesticide runoff.BBC News/Tony JolliffeAmy Fairman represents environmental charity River Action which campaigns for clean and healthy riversBut Red Tractor, which assures 45,000 farms in the UK, have pushed back strongly, calling the finding by the ASA "fundamentally flawed".Jim Mosley, CEO of Red Tractor, told the BBC: "They believe that we have implied an environmental claim. Nowhere in the voiceover or the imagery is any environmental claim actually made."He argued that the ASA only found a minority of people would think the advert meant Red Tractor farms had good environmental standards, and in fact the scheme is focused on other issues."Red Tractor's core purpose is food safety, animal welfare, and traceability. Whilst we have some environmental standards, they are a small part. And as a consequence, we leave that entirely to the Environment Agency to enforce environmental legislation," said Mr Moseley.When asked if that meant Red Tractor does not know if its farms are complying with environmental law, he said: "Correct".But many supermarkets do refer to the environmental benefits of Red Tractor farms.Natalie Smith, Tesco's head of agriculture said last month, on the 25-year anniversary of Red Tractor: "Certification schemes play a key role in providing reassurance for customers, and over the past 25 years, Red Tractor has established itself as a mark of quality, standing for… environmental protection."On Morrisons' website it states: "100% of the fresh pork, beef, lamb, poultry, milk and cheddar cheese we sell in our stores comes from farms certified by Red Tractor, or an approved equivalent scheme, giving customers assurance… environmental protection."Both supermarkets were asked if they stood by the Red Tractor logo.Morrisons did not respond to comment and Tesco referred the BBC to their industry body the British Retail Consortium.The consortium said that "retailers remain committed to working with Red Tractor", but that the organisation themselves are owners of the scheme.
