I am sure it would only be a real issue for vets, and commercial poultry farms
Yeah, I am sure there would be a lot more "teeth" for those folks since they could lose their vet license or operating permits to sell eggs, etc...
Not to split hairs, but Baytril is off label for chickens due to that CDC determination. When you say "Also Baytril, or the drug class fluoroquinolones is actually illegal for food animals not because it is off-label, but because the CDC....", it is actually just one big circle of decisions if you ask me. CDC tells FDA that they don't want Baytril used in animals that might be eaten, so FDA restricts it. Then anyone who used it for food animals is using it off label. Ha! All I will say is that Ebay was happy to sell me some "10 Grams Pure Soluble Enrofloxacin HCl Powder Aquarium Fish Antibiotic Medicine" for when my "fish" get sick. Not trying to sound flippant or anything about the very real world concerns about antibiotic resistance. Because I agree that they are very real concerns. I just have it as a last resort or for a case where it is the only resort due to time or vet availability (even though they aren't supposed to prescribe it), etc....
