In the FARAD Poultry Statistics section of the paper, the final sentence of the first paragraph related to tetracyclines (“In the United States, the egg withdrawal interval for hens following treatment with chlortetracycline needs to be extended from those established in Australia and Ireland to allow residues time to deplete below detection limits.”) should instead be: “In the United States, there are 2 chlortetracycline-medicated feeds approved for use in laying hens.12 When used per label instructions, there is a 0-day egg discard.”
