I think we should not overinterpret this. Lets walk through it backwards.
5% of your body weight in chicken in one day? Assuming you are a small thin person of 55 kg. That means you would need to eat around 2.9 kg of chicken in a day. If you were a 80kg tall person, you’d be looking at eating 4 kg of chicken in a day. Neither is realistic imo.
Now antibiotic resistance bacteria definetly is an issue.
As for harmful bacteria including Salmonella… Unless there is data to compare with from other countries that does not mean much in itself. Raw chicken is notorious for giving food poisioning and being much more dangerous in that regard than raw beef, pork, or even fresh fish. I got a very bad food poisoning from undercooked chicken not to long ago and that was in the EU.
Doesn’t mean that US farming practices aren’t much worse than most EU standards (if enforced), but these metrics mentioned by themselves are not the best indicators for that.
I agree. I think there is better arguments to be made for that though. More interesting than short term health effects would be health effects from long term exposure. Rather than just stating the presence of Bacteria, spread of diseases like “Bird flu” that could also infect humans or the building of multi-resistant Bacteria in industrial farming is more relevant than the presence of Salmonella, which is quite prevalent in chicken, even under good farming practices.
