How long after using Tylan can we start eating eggs?

Abstract

Antimicrobials administered to laying hens may be distributed into egg white or yolk, indicating the importance of evaluating withdrawal times (WDTs) of the pharmaceutical formulations. In the present study, oxytetracycline and tylosin's WDTs were estimated. The concentration and depletion of these molecules in eggs were linked to their pharmacokinetic and physicochemical properties. Twenty-seven Leghorn hens were used: 12 treated with oxytetracycline, 12 treated with tylosin, and 3 remained as an untreated control group. After completion of therapies, eggs were collected daily and drug concentrations in egg white and yolk were assessed. The yolk was used as the target tissue to evaluate the WDT; the results were 9 and 3 days for oxytetracycline and tylosin, respectively. In particular, oxytetracycline has a good oral bioavailability, a moderate apparent volume of distribution, a molecular weight of 460 g/mol, and is lightly liposoluble. Tylosin, a hydrosoluble compound, with a molecular weight of 916 g/mol, has a low oral bioavailability and a low apparent volume of distribution, too. Present results suggest that the WDTs of the studied antimicrobials are strongly influenced by their oral bioavailability, the distribution, and the molecular weight and solubility, and that these properties also influence the distribution between the egg yolk and white.

Injectable

My best guess would be no less than two weeks for the injectable.

Reed this link it is from the FDA sight reed page 6.

"...Withdrawal Times: Because a waiver of the in vivo bioequivalence study was
granted, the withdrawal times are those previously assigned to the pioneer product.
o Chickens must not be slaughtered for food within 24 hours after treatment. Do not use in layers producing eggs for human consumption...."
If the FDA don mean nothing I don't know who does!

Please, lol, still means nothing. Most drugs in the US say not to use in poultry that are producing eggs for human consumption.

I have learned a life's worth of FDA in a matter of 2 years-now 6 years. I got involved with the legalities of electronic cigarettes which are not cigarettes, but personal vaporizors. I have seen the lies and the deceit, the illegal acts by the FDA that were found guilty in courts, and the impact it has had on the rest of society. And all this due to Big Tobacco money nearly supporting the FDA . 40 billion dollars a year in Tobacco tax, and growing buys alot of false and non existent evidence. So I would not trust a word they say-ever. It's money not safety. One drug does not want any competition, and has money, equals other drugs not safe.

There's also alot of B S when it comes to "resistance" of an antibiotic. Resistance is caused by not using antibiotics correctly. Not by using them. And possible resistance can be caused by using the same antibiotic over and over again. They talk about antibiotics used in poultry cause resistance in humans. But I have seen only a few antibiotics that have been used by poultry and humans. And those antibiotics are not even prescribed any more since there are "better" ones now used. Things like Penicillin, ampicillin, tetracycline are old meds compared to what they use now. I really would like to know what antibiotics are Frequently used by poultry and humans at this time. Which specific antibiotics can be used in poultry and cause resistance in humans ? Maybe Amoxicillin? Can anyone set me straight? Maybe I'm missing something.

1 the FDA is the most objective regulator of your country not mine, if you don't believe it I don't know what to say.
2. To understand all the mechanisms of residence to antibiotics learn about plasmids, transformation, conjugation,transductions and the gene transferring in bacteria and you will know why the makes their regulation!
