Ansteckende Vogelgrippe kann in gekühlter Rohmilch 5 Tage lang verbleiben

Researchers just found evidence that influenza viruses that end up in raw milk can infect people for up to 5 days.

Scientists found one particular strain of influenza A virus was still infectious after five days in refrigerated raw milk. The findings suggest that raw milk is a viable transmission route for similar influenza strains—particularly bird flu viruses that are now actively spreading among dairy cows.

This is the first research to examine persistence of influenza in raw milk under more real-world conditions. Raw milk samples were seeded with an H1N1 strain of influenza A. They used a starting dose of the virus similar to the doses seen in contaminated store-brand milk products.

Then they kept the samples refrigerated at a typical temperature and tracked how long it took for levels of viable virus to drop off before it wouldn’t be able to infect someone any longer. They also tested how pasteurization would affect the viability of the virus.

As with other research, they found that pasteurization fully removed the presence of any infectious influenza virus. But it took up to five days for the raw milk samples to no longer be infectious.
