yall made me go look too.
all classes of poultry--now not allowed
EU and Japan - this class of drug only used with extreme restrictions, veterinarian supervision, less than 5 days treatment, longer withdrawal.
the drug is really good, but with a long thought, should be a second choice to pull from medicine box, by conscientious practitioners and herdsman.
because the resistance of gram negative bacteria of this family of drugs is transferable to gram negative bacteria in the environment even without direct exposure to the drug, and for this reason this resistance is detrimental to humans with diseases like salmonellosis and clostridium difficile and other life treating diseases, mostly gram negatives, infecting the human gi tract.
so the rule of thumb for me? choose broadly, and choose baytril lastly.
