Penguins....penguins don't fly.

... and because of that, they're relatively easy to catch - but polar bears do not prey on penguins.

Sometimes I just sit and think. Other times I just sit.

"Researchers at the University of Wisconsin-Madison squirted raw H5N1-containing milk from infected cows into the throats of anesthetized laboratory mice, finding that the virus caused systemic infections after the mice were observed swallowing the dose. The illnesses began quickly, with symptoms of lethargy and ruffled fur starting on day 1. On day 4, the animals were euthanized to prevent extended suffering. Subsequent analysis found that the mice had high levels of H5N1 bird flu virus in their respiratory tracts, as well their hearts, kidneys, spleens, livers, mammary glands, and brains."

Pasteurized and UHT milk should be quite different in this respect.
Though still an issue re spread by animals or vermin with access to raw milk.

Updates on Highly Pathogenic Avian Influenza (HPAI) | FDA
""
Even if virus is detected in raw milk, pasteurization is generally expected to eliminate pathogens to a level that does not pose a risk to consumer health.

I hate to put on my conspiracy hat but the FDA is more or less the same as our Ministry for Primary Industries; product first, people second, until public outrage is greater then industry lobbying.

I'm more keen what the European Commission does.
