Prohibited Drugs and the Reasons They are Prohibited

[casportpony]

I just found this excellent pdf that explains the reasons the prohibited drugs were prohibited.

For those that can't view PDF's I did these screenshots:

Thanks for posting this! There's still too much confusion about this in backyard poultry people, and too many birds improperly treated.
New information leads to new regulations, and new treatments, and finding problems that nobody realized existed. So we all move on and do better; at least I hope so.

OK my definition of Banned, means you cannot purchase them at all. However, my gelding is on phenylbutazone 1 to 2 mg twice a day for sidewinders syndrome. I was also able to purchase metronidazole. This is somewhat confusing to me. I may not be understanding. Any additional advice or information would be most welcomed.

The official story and the truth are often two entirely different things. If the FDA cared about human health then glyphosate would be illegal

I believe this relates only to "food animal" drug safety. Unless you're planning on eating your gelding, it probably doesn't apply.

I was also able to purchase metronidazole.

This one I don't know about. Again, it says it is prohibited for use in food animals, so it would likely still be available for non-food animals (and humans).

Just my best guess here...

Perhaps "prohibited" or "restricted " are better words.

"Most of the prohibited drugs are medically important antimicrobials used in human medicine or have been shown to represent a risk to human health when consumed in products derived from treated animals."

Bute (phenylbutazone) is prohibited for use in dairy cattle over the age of 20 months. It's perfectly acceptable to use it in horses, and since it's not prohibited in anything but dairy cattle, unless the law changed, it could be given to other types of food animals.

Metronidazole (Flagyl) and all other nitroimidazoles are prohibited for use in *all* farm animals.

"Nitroimidazole class
The nitroimidazole family of drugs includes dimetridazole, ipronidazole and metronidazole. Dimetridazole and ipronidazole were originally approved for treatment of blackhead disease in turkeys, a disease caused by parasitic protozoa that affects the liver and cecum. Metronidazole is used in humans for a variety of anaerobic bacterial infections and other parasitic infections. Because this class of compounds has caused tumor production in rodent studies, and because of evidence that associates extralabel use in food animals with potential human health problems, the entire class of compounds is prohibited from use in food animals."

You are correct.

You're correct again. It is FDA approved for humans and can be used "extra-label" in everything but food animals. However, some vets will prescribe it for use in pets that happen to be food animals.

I hear you, but unless the prescribing vet knows that the bute isn't being used on cattle it can be. Even dairy cows. Metronidazole is the only thing other than thyme tincture I've seen recommended to get rid of canker in chickens.
Not arguing, just trying to figure out how they can prohibit certain drugs that they can't really control. You know what I mean?

And the FDA doesn't have anything to do with the herbicides being used. I too wish Roundup was gone!

@casportpony Maybe moving this informative thread to the head of the medical section (sticky thread?) would bring it more to the attention of poultry owners seeking advice for the treatment of their sick and injured birds.
