For several years, preppers and survivalists have turned to veterinary supply houses to purchase antibiotics for use if standard medical care becomes unattainable due to societal collapse or some other major disaster. Unless you really and truly know what you’re doing, I cannot stress enough the danger of going this route.
First of all, with the fish antibiotics (which seem to be the most popular for purchase amongst survivalists), I recently learned that many times the medications being sold are actually expired. What happens is they are manufactured for human consumption. If they are not sold prior to their expiration, they are ok to use on animals for one year. Like anything else, the expiration date may turn out to be somewhat arbitrary but suffice to say that if you’re buying these meds from a vet supply store, odds are good they are past their prime already. Then, they’ll sit in your first aid supply closet for how long before they might need to be used? They do get less effective over time.
Some of these meds, like the tetracycline, don’t degrade over time but actually get more potent and consuming them could damage your kidneys.
Using the wrong antibiotic can result in not only killing off the infection you wish to fight but also negatively impact other bacteria and organisms in your body. Some of those things are actually good for you and killing them off will not help the patient recover.
Plus, misuse of these medications can result in actually strengthening resistant strains of bacteria, making it all that much harder to fight off next time. I’m told that the DEA is starting to clamp down on purchases of animal antibiotics for this reason.
If you are fully trained in the use of these medications and know what you’re doing, more power to you. If you aren’t though, please think twice about it.
