Tools â Egg Withdrawal
Egg Withdrawal Timer
Antibiotic and antiparasitic residues in eggs are a real food safety risk. Know exactly how many days must pass before those eggs are safe to eat.
In development
We're building a database of egg withdrawal periods for drugs commonly used in backyard and small-farm poultry. You'll be able to enter the drug name and treatment start date and get a clear date when eggs are safe again.
Why withdrawal periods matter
Most antibiotics and antiparasitics used in poultry are not approved for laying hens in the US - which means there is no official FDA withdrawal period. This doesn't mean the eggs are automatically safe; it means flock keepers must use their best judgment based on available veterinary literature.
Our withdrawal period data will be sourced from published pharmacokinetic research and reviewed by our veterinary team. We'll be transparent about confidence levels and gaps in the data.
