do such Excessive Antibiotics also get thru into the byproducts, like say chicken meat, eggs & milk?I don't think that eating the residual antibiotics in the animal is the major concern - antibiotics are rapidly excreted and/or broken down in the body.
A larger concern is that this farming technique feeds animals on low levels of antibiotics; not enough antibiotics to kill all the microbes, because animals (and humans) need a microbiome to help digest their food.
- However, this environment, those microbes which are more resistant to this antibiotic will thrive, while those that are susceptible will die - evolutionary pressure.
- That means that antibiotic resistance will quickly increase in such an environment: Bacteria engage in "Horizontal gene transfer", where useful genes are passed between different species of bacteria
- A combination of antibiotic resistance and a bacteria that is dangerous to humans is an even more dangerous combination.
People working closely with animals are more likely to pick up microbes from them - including antibiotic-resistant microbes.
- And people who eat the meat will tend to pick up antibiotic-resistant bacteria from the food, especially if it is not properly cooked.
There is a similar concern about increasing antibiotic resistance in farm soil (antibiotic-rich urine) and streams (due to antibiotic-rich farm runoff).
Colonization by antibiotic resistant bacteria is not in itself particularly dangerous - until the bacteria get into a sore or the bloodstream, and then our favorite tools for dealing with bacteria are suddenly ineffective.
