Personally that is my feeling too, I tend to keep my immune system well exercised and don't worry much about eating my own chickens and their eggs which have been exposed to wormers and antibiotics. But for some people that might have weaker immune systems it might not be a risk worth taking. Certainly when general regs and licencing of antibiotics is set out it is done targeting large scale farming products sold to the public with the whole general population in mind including those that might have weaker immune systems.
I think there are some differences though depending on which antibiotics, some sound like they tend to encorage the development of antibiotic resistant bacteria more than others. Also the doctors have more worries about some drug resistance than others. For example not as big a worry about a germ becoming resistant to penicilin as ther would be to newer more powerfull antibiotics. So much is resistant to penicilian now that it is not a worry like it is if one of the last resort antibiotics becomes ineffective.
If anyone is going to use antibiotics, esp off lable best they do their homework so they at least know the risks and make informed decisions.
Just seam so many people give advice about egg and meat withdrawal periods that are not consistent with what is set out by manufacturers or regulatory bodies. One never knows if they are giving advice to a healthy person who will have no issues with respect to eating eggs or someone who might have a weakened system and could be made very sick.
