a 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 if 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.
