In Europe, bird flu has not yet been detected in cattle, but unpasteurized milk is still not recommended for consumption. Meanwhile, in the United States, bird flu has spread to ranches and affected 42 dairy herds in nine states. The first observation of the disease was made on a Texas farm where the virus was found to be secreted in milk. Cows have shown symptoms such as decreased milk production, decreased appetite, fever, and fatigue.
Livestock farm workers are at risk of infection due to close contact with cows, their manure, and milk. While at least one person in contact with the livestock has been confirmed to have bird flu, they only showed mild symptoms. Workers on these farms, mainly Spanish-speaking immigrants, may have limited access to healthcare and sick leave.
In Finland, bird flu has not been detected in birds this spring, but precautions should still be taken to prevent its spread. For instance, dead birds from pastures should be collected promptly and feed protected from contamination. Despite the lack of a major infection risk, consumers are advised not to drink unpasteurized milk as past outbreaks of bird flu in Finnish fur farms have raised concerns about its contagion to humans. The Ministry of Agriculture and Forestry may issue regulations if needed to prevent the spread of bird flu in cattle.
Overall, various precautions and monitoring measures are being put in place to control the spread of bird flu and protect both animals and humans from its harmful effects.
