The National School Lunch Program accounts for roughly 7.5% of U.S. fluid milk sales.
A 2017 peer-reviewed study found that among younger elementary students, 45.5 % of milk offered was wasted over the course of the week.

A recent review of oral stereotypic behaviours in farm animals reports that in one observational trial of dairy cows, tongue-rolling was found in ~29% of cows (2,365/8,158).
73% of dairy revenues come from some form of subsidy.

A U.S. abstract reports that ~29% of cows (2,931 animals) were observed tongue-rolling at least once during a milking in a large U.S. herd (also noted ~6% had more frequent behaviour).

A general veterinary text states: “All dairy herds have cows with subclinical mastitis; however, prevalence of infected cows varies from 5 % to 75 %, and quarters from 2 % to 40 %.”

The USDA Animal and Plant Health Inspection Service “Dairy 2007” study looked at herd-level prevalence of contagious mastitis pathogens: e.g., 43 % of operations had herds testing positive for Staphylococcus aureus contamination in bulk-tank samples.

According to the National Mastitis Council (cited via a multistate project summary), “approximately **38 % of dairy cows in the United States experience clinical signs of disease [mastitis]”.

An extension article summarizing U.S./North American data reports that in one slaughter-plant audit dairy cows had ≈ 48.6% lame (vs 16.2% beef cows) in that dataset.

And if that makes executives uncomfortable?
Good. Discomfort is where change begins.
Our patients don’t get a voice in these boardrooms.
But veterinarians do.

This administration can sure use someone like you, asking the questions that need to be answered for ensuring biosafety.
But, as you know, it's not going to happen because they are already full of bull....

What about the workers? What about nearby poultry facilities? Aerosolized milk particles are everywhere in milking parlors. The recent study showed virus is everywhere on facilities. Dairy production represents a biosecurity threat that is impossible to contain.

Could 1mL of raw, H5N1-infected milk potentially infect 10,000 to 100,000,000 turkeys?
Obviously, these lab titers don’t translate cleanly into real-world transmission because dose, route, strain, host species, and environmental factors all matter...

So, I'm just thinking out loud here, say raw milk has on the order of 10^4 to 10^9 virus particles per mL, and it takes fewer than 10 virus particles to infect 50% of turkeys—assuming similar strain, lab, and host conditions...
