Health authorities have reassured consumers that the spread of bird flu to dairy cows in several US states poses a low risk to human health.

However, this has not stopped the story from dominating news headlines and drawing attention to a potential link between intensive animal farming and disease transmission.

The US Department of Agriculture (USDA), the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) confirmed the spread of bird flu in sick cattle from dairy farms in Kansas and Texas.

Subsequently, a person in Texas was diagnosed with a highly virulent strain of bird flu, representing only the second human case of this strain of bird flu ever detected in the US.

The CDC emphasised that the public has a low risk of catching the virus, which can spread through close contact with infected birds. Moreover, the USDA did not expect the bird flu cases in cattle to affect food safety or supply in the US, given that pasteurisation kills off bacteria and viruses, including this strain of bird flu.

Katrina Diamonon, Principal Analyst at GlobalData, comments: “Despite assurances from health authorities, it will be difficult for consumers to detach this concerning news story from their own experiences. Many will inevitably be worried about how the spread of this virus may affect the safety of the meat and dairy products they consume.

“There is also residual anxiety and fear following the unprecedented and devastating impacts of the Covid-19 pandemic. Even though there is no definitive proof of how the pandemic started, one prominent theory is that the virus emerged in wild animals and spread to humans at the market. This has naturally served to raise suspicion about the meat supply chain and cause consumers to rethink their choices.”

A survey conducted by GlobalData found that over one-quarter (27%) of consumers globally would consume plant-based meat or dairy alternatives for safety reasons, underscoring the perceived risks that some consumers associate with traditional animal-based products.

Diamonon concludes: “It is crucial to establish consumer confidence in products through clear labeling, certifications, and seals, as well as traceability and supply chain information. No brand is immune from food safety scares, but proactive reassurances from brands can help regain consumer trust.”
