Safeguard/Fenbendazole egg withdrawal period...okay to feed eggs to dogs?

[HannahGillie]

Hi everyone, I had to deworm all of my chickens for gape worm about a week ago (everyone is doing much better now!), but I read that there is an egg withdrawal period after deworming with fenbendazole afterwards. I have seen its anywhere from a week to 2.5 weeks. Either way, I wanted to ask if it is safe to feed the eggs to my dogs? I hate to just throw the eggs out, and I know fenbendazole is a dewomer used for dogs, so my thought process is that if it is safe for them to take as a dewomer already, the eggs from chickens treated with the same medication should also be okay? Or am I wrong? Just wanted to ask and be safe

Thanks!

I would think the same thing, that it would probably be safe for the dogs (depending on the total amount of dewormer involved).

But I would be worried about creating resistant parasites. If you give a low dose of wormer to any animal, it kills the most susceptible worms, but lets the more resistant worms survive to pass on their genes. Over time, that breeds a set of parasites that cannot be killed by the wormer you were using. This is a problem in all kinds of animals, not just chickens or dogs.

Do you know that Fenbendazole is safe for humans too! It even has Anticancer properties!
