Medicated feed

[erik67]

I have been using medicated feed on my chickens because of a sickness they all had they were having breathing problems and runny nose . Is it ok to eat the eggs or should I wait till the treatment is over I'm supposed to only use the med feed for up to 14 days

The feed has chortetracyiclein in it I may have misspelled it

Chlortetracycline?

Antibiotic, I believe... I think k there should be a withdrawal period of two weeks on that, if I'm not mistaken....

Chlortetracycline is a wide spectrum antibiotic.
Are you sure the breathing problem and runny nose wasn't from a virus, fungus, protozoa, nutrition, environmental issue or even a bacteria that can't be cured with a general antibiotic?

This drug is no longer approved for use in laying hens, and so there is no approved withdrawal time for eggs, because there will always be some level of drug residue in their eggs. Look at the farad.org site for more information. Mary

Yeah, I thought it was for bovines and equines.

Ah yes, we just discussed this not to long ago on another thread, didn't we?

Good catch Mary

I searched the site posted a few back and couldn't find chlortetracycline in unapproved or no extra-label use or limited extra-label use. The link I put in above is for studies in Australia. Couldn't find USDA studies in short time of searching.

In studies on a multitude of animal species there is indeed a withdrawal period for chlortetracycline. For our purpose, the chicken, and in approved dosage (check the study in link) the withdrawal time for no detection of chlortetracycline in a chickens fat or liver is day 3.

That's all changing as of now, @Egghead Jr.... Here's the thread where it was discussed at length recently.
