Many poultry species are considered food-producing animal species, and as such, these species are
regulated by the U.S. Food and Drug Administration (FDA). 166 Even the individual animals of any of these
species are never used for food, they are still regulated by the FDA. The FDA prohibits the use of certain
drugs, with no allowable extra-label drug use, in any food-producing animal species. These prohibited
drugs are clearly identified in the tables, and the doses are provided in case they are needed for a
similar but non-food-producing animal species (e.g., Attwater’s prairie chicken), and listings should in no
way be misconstrued as an endorsement of using FDA-prohibited drugs in any food-producing animal
species. Please refer to the appropriate tables at the end of this chapter regarding the definitions of
prohibited drugs, extra-label drugs, labeled drugs, and drugs needing a Veterinary Feed Directive prior to
choosing a drug and dose. Please refer to the Food Animal Residue Avoidance Databank at
www.farad.org and other sources listed in Table 6.25 for meat and egg withdrawal times. 54
