Bovaer, a feed additive designed to reduce methane emissions in livestock, has been touted as a potential solution to combat what is referred to as “climate change” in an attempt to make animal agriculture more “sustainable”. However, consumers should approach its use with caution, especially when considering its implications for both human health, animal welfare and the integrity of healthy farming practices.

One of the key reasons for concern is that Bovaer, like many chemical feed additives, is not permitted on organic farms. Organic farming standards prioritize natural methods, focusing on the health of the soil, animals and the environment. It would appear this natural healthy approach is no longer in vogue in some Australian supermarket chains! 

The use of synthetic additives like Bovaer in non-organic meat and dairy production is rising with Coles commencing the use of Bovaer back in 2022 and stating “Coles is expanding the use of the methane reducing feed supplement Bovaer”. It is currently used exclusively for the supermarkets 'Finest Carbon Neutral' line of products. Coles has tried to assure consumers that this additive is safe citing it has been used overseas for 15 years. You might recall farming practices that led to Mad Cow Disease (Bovine Spongiform Encephalopathy, or BSE) were also considered safe for decades (started back in 1970) and resulted in a major outbreak in 1990.

Woolworths and Aldi have, on the back of significant public back lash, made public announcements more recently stating that their meat and dairy suppliers were not currently known to be using this chemical.

There are health concerns that Bovaer may increase the risk of certain cancers and reduce fertility rates as shown in studies with rats and mice exposed to high doses of this chemical. Naturally, the company selling this chemical and farms using it claim it is safe for you and its only effect on the meat or dairy is just how much cows fart!  

The long-term impacts of Bovaer on livestock health, biodiversity, and the ecosystem remain unclear. As does the long term effects on humans who consume these affected products. While it may partially reduce methane emissions, we must consider potential side effects or unintended consequences that could arise from its widespread use. Consumers should be aware that just because a product is marketed as "sustainable" or "climate-friendly," it doesn't always align with the values of transparency and health of the end consumer.

Ultimately, for those of us who prioritise our health, animal welfare and ethical and environmentally friendly food production, we need to decide at the checkout if we financially support this new farming practice.
