Pennsylvania is ramping up efforts to protect its dairy industry and public health from avian influenza. State veterinarian Dr. Alex Hamberg emphasizes the crucial role of milk testing in achieving this goal.
A free weekly bulk tank testing program, launched last month, aims to boost consumer confidence in milk safety, prevent the spread of the virus between farms, and safeguard public health. Despite the program's benefits, only a handful of Pennsylvania's nearly 5,000 dairies have enrolled so far.
Hamberg stresses the importance of early reporting of suspicious illnesses to veterinarians or the agriculture department. Delayed reporting in another state led to a significant outbreak on an adjacent poultry farm, highlighting the potential consequences of inaction.
Avian influenza can be detected in milk up to two weeks before cows show symptoms, enabling early identification and response to infections. While no cases have been reported in Pennsylvania yet, the virus has affected over 140 dairy herds across 12 states.
Importantly, pasteurization effectively kills the virus, ensuring the safety of milk for consumption. However, there have been cases of dairy farm workers experiencing eye infections and respiratory symptoms after exposure to infected milk.
To minimize risks, Hamberg recommends using protective gear, such as masks, face shields, and gloves, for individuals working with cows or raw milk. Pregnant women, the elderly, and those with respiratory or immune issues are considered high-risk groups.
“We wouldn’t be having all these calls (with industry) if this was just something that would cause mild conjunctivitis in dairy workers,” said Dr. Miriam Wamsley, a respiratory virus epidemiologist at the state Health Department.
By prioritizing milk testing, early reporting, and preventive measures, Pennsylvania aims to safeguard its dairy industry and public health from the growing threat of avian influenza.
