1) The vast majority of consumed meat comes from animals that have so closely co-evolved with humans that any pathogens that can plausibly jump from one to the other already has (with sometimes devastating effect). If we simply limited meat consumption to cows, pigs, and chicken, it'd satisfy most people and strictly limit the risk of novel zoonetic pathogens.
2) Those diseases you list in particular are mostly unconvincing: SARS and COVID likely come from bats via civets, MERS from bats via camels, Ebola from bats via primates. None of these species make up most meat consumption.
3) E. coli is the best example, but plenty of people do get it from lettuce and spinach. That said, E. coli is never going to shut down the world in a mass pandemic.
What do you think about H5N1 (Avian Flu)? This is an example of a disease carried by birds, passed to domesticated birds, and then on to humans. What about H1N1 (Swine Flu)? Both of these diseases required culling millions of livestock due to the very real crossover to human populations globally.
Are you aware that there are intermediate hosts in many coronavirus epidemics? Many of those involve domesticated livestock such as chickens, pigs, and cows[1].
E. coli isn't naturally found on greens since it requires an animal host. How does it keep getting there? Interaction with domestic livestock[2].
If we are going to continue our interaction with livestock in the way we are now, we should at least all be aware that this is a conscious choice which will result in pandemics on a somewhat regular basis.
