Abstract:
In 2005, the FDA withdrew approval for the use of fluoroquinolones in live poultry production. To assess any changes in countable numbers of ciprofloxacin-resistant Campylobacter before and after the fluoroquinolone withdrawal, retail whole raw chicken carcasses (RTCC) purchased in Northwest Arkansas from 2004 to 2006 were sampled for this purpose. Using a previously published direct-plating method developed in our laboratory, we quantified trends of Campylobacter and ciprofloxacin-resistant Campylobacter loads by direct plating whole chicken carcass rinses on Campylobacter agar (CA) or Campylobacter agar containing 8.6 mg/ml ciprofloxacin (CCA). Countable populations of Campylobacter were recovered from 74, 96, and 63% of carcasses sampled in 2004, 2005, and 2006 respectively. The percentages of carcasses with minimum detectable levels of ciprofloxacin-resistant Campylobacter were 20, 42 and 33%, sampled in 2004, 2005 and 2006, respectively. Our 3 year analysis in one geographical area indicated a persistence of Campylobacter and ciprofloxacin-resistant Campylobacter on retail raw chicken carcasses despite the cessation of fluoroquinolone use in poultry production.
