I was planning on using Wazine first followed up by Safeguard 10 days later. Between giving the 2 meds and the waiting period I would be throwing out 150 eggs which I don't want to do. I can somewhat understand throwing out eggs after antibiotic treatment, because of antibiotic resistance, but what is so harmful about possibly ingesting trace amounts of worming meds? The active ingredient in Wazine is piperazine, and this is prescribed in humans for pinworms. So it has been proven safe for humans. Unless someone is pregnant or allergic to sulfa drugs I can't see why it would hurt to eat trace amounts in eggs. As for the active ingredient in Safeguard - fenbendazole - this is not prescribed in humans but the FDA has tested it on people with no ill effects. It seems there are a lot of people taking it anyway to treat parasitic infections at home. Does anyone know of any studies that prove how much of these medications get absorbed into the egg, or why it is considered unsafe for humans? I'm just wondering where the advice of throwing out eggs for weeks comes from - as in, is there any evidence to support why? Has anyone here ignored that advice and eaten eggs anyway?
