Id hazard a guess that live virus contact with people on scale is what — by chance — eventually selects a cross over strain. So virus that can be cultured into existence of out of milk presents a possible vector for that. Hence they are testing to see if they can grow the virus from milk samples.

mixing milk dramatically increases these chances. If each person drinks milk from one cow, and there are 1 million of each, then you have 1 million chances. A chance is higher if a cow has a few mutations in its viruses, or if a person has a slightly different receptor or immune system... But if you put all the milk from the 1 million cows in a mixing vat and then distribute it to the same 1 million people, now there are 1 trillion chances, and the slightly better mutations will end up coming into contact with the humans with slightly more receptive cells. This is one of many reasons I think we should limit the fanin/fanout of food production. Ie. you may only mix animal products in say batches of up to 10,000 cows, and that batch may only be split up amongst up to 10,000 humans. Then you have to clean the production equipment before the next batch.

  The virus is killed by pasteurization. There is no live virus in the milk.

      Please don't inject milk into your muscle tissue.

    Milk in the US is pasteurized at 63C for 30 minutes. > The results show that at 54.5 °C, the virus [SARS-CoV-2] half-life was 10.8 ± 3.0 min and the time for a 90% decrease in infectivity was 35.4 ± 9.0 min. [1] At 8.5 degrees hotter, I'm sure stuff happens quicker, but I doubt very much it kills them all. This study is in air - in liquid I imagine they would survive to a higher temperature. It's far from clear that all virus particles are inactivated by pasteurization. Remember the main purpose of pasteurization is to kill most bacteria, to increase shelf life.

  I have a similar theory with ground meat, or even where you're buying individual cuts. People are now consuming hundreds of thousands of animals throughout their lifetime rather than hundreds or thousands.

    Plenty of studies have shown "processed food" (ie. hotdogs) leads to poorer health outcomes. Processed food, in general, comes from far more individual animals than other foods.

      I'm talking about infectious vectors. Hotdogs and other processes foods are generally paturized or cured. That could still be a vector for things like prions though.
