Dairy workers | Disease control body issues employee safety warning over bird-flu risks

The Centers for Disease Control and Prevention (CDC) has issued a warning to dairy workers regarding the potential risks of H5N1 bird flu transmission.

The CDC is calling for heightened safety measures and expanded testing in response to an uptick in infections.

Since March, it has confirmed 52 cases of bird flu among humans and outbreaks in 505 dairy herds across 15 states. While human-to-human transmission has not been reported, experts caution that the virus's spread among animals increases the risk of mutation, potentially elevating the threat to humans.

Workplace bird-flu exposure

Dr. Abraar Koran, infectious disease Doctor and Researcher at Stanford University, pointed to workplace exposure as a likely source of infections.

"We suspect the virus has been transmitting through spilled milk splashing into workers' faces during routine dairy operations," he said. Symptoms commonly reported include conjunctivitis, an eye infection associated with exposure to the virus.

The CDC is urging dairy workers to use protective gear, such as gloves and face shields, to reduce the risk of exposure. The agency is also expanding testing efforts to identify cases early, especially among those experiencing mild or asymptomatic infections that might otherwise go undiagnosed.

Prevention by pasteurization

While concerns about consuming raw milk have surfaced, Dr. Koran emphasized the importance of pasteurization.

"We have not observed transmission through raw milk consumption, but viruses are constantly evolving. Pasteurization effectively kills the virus, providing a safe option for consumers," she said.

The CDC’s call for action underscores broader dairy worker safety concerns as the agriculture industry grapples with the spread of avian influenza. By adhering to recommended precautions and enhancing monitoring, experts hope to mitigate risks while safeguarding both workers and the food supply chain.

The CDC is advising dairy operations to stay updated on guidance and implement biosecurity protocols to curb potential transmission.
