Bovaer - What You May Have Missed - The Great Climate Con

Bovaer - What You May Have Missed

The climate cult are coming for our food and we have to stop them!

The climate cult are coming for our food supply with the toxic feed additive Bovaer, since announcing trials in the UK confusion has arisen to what parts of our food chain have been infected and whats happening next, time to clear that up and also highlight once again why we don’t want this new drug anywhere near our food supply.

The Case Against Bovaer: Why This Feed Additive Has No Place in Our Food Supply

As informed citizens and advocates for health, transparency, truth, and ethical food systems, we must scrutinise interventions like Bovaer, a feed additive marketed as a solution to reduce methane emissions from cows. While its proponents claim it’s a step toward combating climate change, a deeper examination reveals significant concerns about its safety, necessity, and long-term implications for human health, animal welfare, and the environment. Also, who said this climate is the perfect and we shouldn’t welcome some mild warming and that cows have any impact on this anyway? As someone who rejects the narrative that CO2 is a pollutant and understands the biogenic carbon cycle—where cows, grazing on grass, play a vital role in regenerating soil and sustaining ecosystems—I believe Bovaer represents an unnecessary and risky intrusion into our food supply. Below, I address the most commonly asked questions about Bovaer, drawing on available evidence to highlight why it should be kept out of our food system entirely.

What Is Bovaer, and Why Is It Being Used?

Bovaer is a feed additive developed by DSM-Firmenich, a Swiss-Dutch company, designed to reduce methane emissions from cattle by inhibiting an enzyme in the cow’s rumen that produces methane during digestion. Its active ingredient, 3-nitrooxypropanol (3-NOP), is combined with silicon dioxide and propylene glycol. It’s being trialed in over 68 countries, including the UK, US, and Australia, with companies like Arla Foods partnering with supermarkets like Tesco and Aldi to implement it in dairy farming. Proponents claim it can reduce methane emissions by 27-90%, depending on dosage, presenting it as a tool to address climate change. As can be seen in these charts about CO2, mans impact on climate is tiny. Pollution of our own habitat and chemical overload of our society and people is a far bigger issue which Bovaer only worsens.

However, this premise rests on the flawed assumption that methane from cows is a significant driver of environmental harm. Cows are integral to the biogenic carbon cycle, where methane from their digestion breaks down into CO2 and water within 7-12 years, which is then reabsorbed by plants like grass to restart the cycle. This process is circular and natural. Grass-fed cattle enhance soil health, use land that otherwise wouldn’t have any agricultural use, feed the population with high nutrient food, making them essential to human society and nature, rather than planet destroyers, cows are a gift. Introducing Bovaer disrupts this natural system under the guise of environmentalism, raising serious questions about its necessity and safety.

Is Bovaer Safe for Human Consumption?

The safety of Bovaer for consumers is a major concern, particularly given the warnings about its active ingredient, 3-NOP. The U.S. Food and Drug Administration (FDA) explicitly states that 3-NOP “may damage male fertility and reproductive organs, is potentially harmful when inhaled, and is a skin and eye irritant,” requiring protective gear for those handling it. While regulators and manufacturers claim that 3-NOP is metabolized in the cow’s rumen and does not appear in milk or meat, studies have detected its metabolite, 3-nitrooxypropionic acid (NOPA), in cow’s milk at 80% of the proposed use level. This raises red flags about the claim that Bovaer poses no risk to consumers.

The European Food Safety Authority (EFSA) acknowledges that 3-NOP’s genotoxicity and carcinogenicity have not been fully clarified, and high doses in animal studies (300-500 mg/kg body weight) caused testicular shrinkage and reduced sperm count in rats, mice, and dogs. While regulators argue that the doses used in cattle are far lower (around 0.2 grams of 3-NOP daily), the lack of long-term studies leaves uncertainty about cumulative effects. For a 70 kg human, achieving the toxic dose seen in animal studies would require consuming 21-35 grams of pure 3-NOP daily—an unlikely scenario—but the presence of NOPA in milk suggests some exposure is possible. Without transparent, independent, long-term studies, we cannot trust assurances that Bovaer is safe for humans consuming dairy or beef from treated cows. Once again another chemical with potentially big negative side effects making its way into our bodies. Not needed and not helpful.

Below is kinda what people should look like whilst handling Bovaer at high concentrations and we’re supposed to be ok with this entering the animals whose milk we consume!?

Is Bovaer Being Fed To Meat Cows?

No, currently in the UK Bovaer is only being trialled in cows for dairy farming. We need to keep it that way because eating meat is good for the planet as it is. This article will help you know all you need to know about Bovaer and then you just need to become good at debating to change the courses of conversation and we can together, change the culture of our society.

Does Bovaer Affect Male Fertility?

One of the most alarming concerns about Bovaer is its potential to impact male fertility. Animal studies, including those reviewed by Japan’s Food Safety Commission, found that 3-NOP reduced testis and epididymis weight, sperm count, and sperm motility in rodents and dogs at doses above 100 mg/kg body weight. The EFSA noted effects in rat testes at 300 mg/kg, far higher than the acceptable daily intake of 0.3 mg/kg set by the UK Food Standards Agency (FSA). However, the presence of NOPA in milk, even at low concentrations, raises questions about whether chronic, low-level exposure could disrupt human reproductive health over time.

The mechanism by which 3-NOP affects fertility is not fully understood but may involve hormonal disruption or cellular damage in reproductive tissues. Given the rising global concerns about declining male fertility rates, introducing a compound with known reproductive toxicity in animals into the food chain is reckless. The absence of long-term human studies and the reliance on short-term data from industry-funded research only heighten these concerns. Then add in how it is completely unnecessary to even be trialing Bovaer because cows are not planet destroyers and we have to deeply question the motives of those involved. It’s probably layers of incompetence wrapped in a nice blanket of fear with some greed thrown in and maybe elite evil right at the top of it all.

Is Bovaer Safe for Cows?

Bovaer’s impact on cow health is another critical issue. While the EFSA concluded that Bovaer is safe for dairy cows at the recommended dose of 100 mg 3-NOP/kg dry matter, some studies reported reduced feed intake and lower heart weights at higher doses. Altering the rumen’s natural methane production process could disrupt the cow’s microbiome, which is essential for digestion and overall health. The long-term effects of this interference are largely unknown, as most studies are short-term and industry-sponsored.

Cows are not planet destroyers; their grazing supports regenerative agriculture, and enhancing ecosystem resilience. Introducing a synthetic additive like Bovaer risks compromising their health and the quality of their milk and meat, potentially undermining the very systems that make grass-fed cattle vital to sustainable farming. Ethical concerns about subjecting animals to untested, long-term interventions further underscore the need to reject Bovaer.

Did The Bovaer Trial End In The UK?

As advocates for a safe, sustainable food system, we face a troubling lack of clarity about Arla Foods’ 90-day Bovaer trial, launched November 26, 2024, across 30 UK farms. Intended to end around February 24, 2025, no public confirmation verifies its conclusion, leaving consumers in the dark about whether Bovaer persists in Arla’s supply chain. The absence of results, coupled with the detection of Bovaer’s metabolite, 3-nitrooxypropionic acid (NOPA), in milk, fuels distrust.

At the time of writing a freedom of information request has been sent to the food standards agency to determine if Arla has continued on with using Bovaer.

Meanwhile, Müller UK’s trial, involving 40 farms out of about 1000 they operate, supplying Sainsbury’s and Co-op, is confirmed ongoing as of June 2025, with no end date disclosed. This persistence heightens concerns about Bovaer’s spread, especially without labeling to inform consumers. The FDA’s warnings about 3-NOP’s reproductive toxicity and skin/eye irritation underscore the urgency of knowing its status. Cows, far from planet destroyers, are vital to regenerative ecosystems, making Bovaer an unnecessary risk. We must demand answers through FOI requests to the Food Standards Agency, political pressure via MPs like Rupert Lowe, and boycotts of Müller and Arla products. Opting for organic dairy or Bovaer-free farms like Hook & Son ensures safety while we push for accountability. Transparency is non-negotiable—our food supply’s integrity depends on it.

What Products And Supermarkets Potentially Have Milk From Cows Feed Bovaer?

The following retailers and products are definitely linked to Müller’s supply chain and may contain milk from Bovaer-fed cows:

Sainsbury’s Own-Brand Dairy Products:
Sainsbury’s own-brand milk, butter, cheese, and yogurt. Müller processes milk for Sainsbury’s, and the 40 farms trialing Bovaer are part of this supply chain. Note that Sainsbury’s own-brand organic cheese, made by Wyke Farms, is Bovaer-free due to organic standard
Co-op Own-Brand Dairy Products:

Products: Co-op’s own-brand milk, butter, cheese, and yogurt. Müller supplies the Co-op, and the 40 farms trialing Bovaer are part of this supply chain.
Müller-Branded Products:

Müller’s own branded items, such as Müller Milk, Müller Corner yogurts, and Müller Butter, available at various retailers (e.g., Tesco, Asda, Sainsbury’s, Co-op). While not all Müller products come from the 40 trial farms, the integration of milk from these farms into Müller’s processing makes it possible.

Arla’s 90-day Bovaer trial, involving 30 farms, began on November 26, 2024, and was expected to end around February 24, 2025. No explicit confirmation of its conclusion or continuation exists, but Arla’s commitment to continue despite backlash suggests potential ongoing use. If the trial has extended or Bovaer has been adopted more broadly, the following sources may be affected:

Arla-Branded Products:

Lurpak butter
Cravendale milk
Arla Protein shakes and yogurts
Arla Lactofree dairy products
Arla BOB (Best of Both) milk
Anchor butter
Apetina cheese
Castello cheese

Supermarket Own-Brand Dairy Products:

To summarise simply, every major supermarket homebrand products are possibly impacted due to Arla being the largest supplier of milk by far. A few exceptions apply and the likelihood it is in every pint of milk, slab of butter and block of cheese at this point is low due to the low number of farms in the trial, however unfortunately we cannot be sure. This is once again highlighting the importance of buying high quality, organic and local products because when the control of food production is in the hands of nameless entities the whole game becomes much harder.

- Tesco
  - Products: Tesco’s own-brand milk, butter, cheese, and yogurt sourced from Arla. Tesco’s Future Dairy Partnership with Arla increases the likelihood of Bovaer-derived milk in these products if the trial has continued.

Conclusion

The addition of Bovaer to our food supply is a massive overreach from the climate cult. It is not needed in anyway and it is potentially very dangerous and may even have negative effects on fertility which is a huge thing considering the current fertility rates in the west. This is why such a huge backlash came from the public. Now we just need to know if Arla have continued it’s trials or not. Hopefully the FOI will help us with this and we need to push for transparency wherever we can. Ultimately the most important thing any of us can do is shop local and organic wherever possible. Voting with your money is a power often understated and we may like to save a few pennies to get cheaper however it will collectively come back to bite us big time if we completely lose control over our food supply.

A good example of how learning more and educating our communities is crucial is how the Norfolk residents currently under siege by the climate cult looking to steal their land in the name of more solar panels would have their fight be much more effective if they knew the truth about The Climate Con at large.
