Fluoroquinolones are approved for use in poultry.

• A. True
• B. False – approved in 1996 but withdrawn in 2005
• C. False – they were never approved for poultry
• D. False – they are currently approved for all poultry

Answer: (B)

The key idea is how regulatory status of antibiotics in food animals can change over time. Fluoroquinolones, such as enrofloxacin, were approved for use in poultry in 1996 to treat diseases in chickens and turkeys. However, due to concerns about promoting fluoroquinolone-resistant bacteria, the FDA withdrew these approvals in 2005. Since then, fluoroquinolones are not approved for use in poultry. So the statement is not correct in current practice, even though there was an approval in 1996 followed by withdrawal in 2005. The other options are inconsistent with this history: they imply current approval or no approval at all, which doesn’t match the withdrawal timeline.
