It should be noted that this is just a method to determine the amount of infected cows. The milk itself isn't a threat to anyone. Virus fragments in themselves can't do anything, they're just a sign of the original cow problem.
Call out anyone that tries to fearmonger about the milk being dangerous.
The bigger concern, that not many people are taking about, is wildlife. This bird flu is spreading out in the wild and has been taking out all sorts of endangered birds and mammals in mass quantities.
And if something jumps into humans, it’s more likely to happen from the massive spread happening in local wildlife.
From what I've read it doesn't seem to be a particularly severe disease for cows anyway. The hubbub is mostly about the potential for farm and dairy workers to catch it directly from a cow, which still seems like an incredibly rare occurrence
Health officials maintain — and experts agree — that pasteurized milk is safe to drink. The FDA detected small pieces of the virus in milk, not live, infectious virus.
“Right now, all indication is that pasteurization is effective,” said Dr. Andrew Bowman, a veterinary epidemiologist at Ohio State University.
Yeah, any DNA or RNA in there is going to be completely denatured because of the pasteurization. But that doesn't mean the physical components of the genes just goes away. It is made ineffective and harmless, but it serves as a useful measure on how many cows are infected.
Concerning infrastructure investment, we should really put a lot into waste measurement everywhere for issues that affect health. It's the best alarm for growing problems at a large scale sampling that can't be fudged or missed. Many areas have all but stopped constant monitoring because of budget.
