The alleged increase in microbial risk and infectious disease in communities in the past several years apparently has been driven by the rapid and occasionally dramatic emergence of food-borne bacteria that are resistant to common antimicrobial drugs. These possible changes prompted regulatory proceedings1 regarding fluoroquinolones and their use in food-producing animals, particularly chickens, due to the increase in resistance among Campylobacter jejuni. The issue relating to Campylobacter jejuni is that resistance to fluoroquinolones in human Campylobacter jejuni isolates increased from zero in 1991 to high levels (13%) soon after the introduction of fluoroquinolones in chickens in the USA. Apparently similar data were previously reported from Europe, where increases in ciprofloxacin resistance rates (from 0% in 1982 to 11% in 1989) among human isolates of C. jejuni were allegedly caused by fluoroquinolone use in chickens2. The purpose of this brief communication is to offer another perspective on resistance trends related to this subject.
