Dr Bones & Amy talk about the tetracycline myth as well.
There actually wasn’t any study done to determine if “expired” tetracycline caused renal failure. This myth is based on one incident where someone died, unobserved, of renal failure. They found out he had taken “expired” tetracycline and just blamed it on that without any real connection besides circumstances.
I’m pretty much in agreement re: the tetracycline stuff. I know if I open a sealed pac of vet tetracycline, there is a certain consistency and color to it, and as long as it holds those that tells me it has not been exposed to excessive heat or moisture.
And even if a person was suspicious about it, I’m not sure I would throw it away! It could still be dissolved in water and used topically. It could be dissolved in water and used as a mouth rinse in the case of toothaches, etc. as long as the person was careful to gargle good with fresh water and spit it out after.
It’s common sense, really.
I know I asked at the Farm supply about liquid Penicillin. They said it was good long after the expiration date BUT!!! IF IT TURNS YELLOW, PITCH IT!!
And these people know. I mean they use the stuff on multi-million dollar race horses, prize bovine breeding stock, and even though doctors and pharma experts uniformly say that we get too much antibiotic residue from eating things like chicken, that residue IS NOT CONTAMINATED, it’s NOT POISONOUS, so there ya go!
