Abstract
Human campylobacteriosis has become the major cause of foodborne gastroenteritis in industrialized countries. Although there have been numerous studies investigating the prevalence of Campylobacter in animals and raw meat, sensitive and low-cost detection methods are needed to implement effective control measures during primary production and to use as tools in risk assessment studies. Thermophilic Campylobacter spp. in naturally contaminated (n = 64) and inoculated (n = 16) broiler samples were detected using two International Organization for Standardization (ISO)-approved methods. Both enrichment broths (those of Preston and of Park and Sanders) were inoculated with (i) Campylobacter jejuni ATCC35921, (ii) boneless breast from broilers, (iii) boneless breast rinse solution, (iv) boneless breast rinse solution inoculated with C. jejuni ATCC35921 before centrifugation, and (v) boneless breast rinse solution inoculated with C. jejuni ATCC35921 after centrifugation. The results indicated that the Park and Sanders broth was superior to the Preston broth for recovery of Campylobacter spp., and no significant differences (P > 0.05) were found between ISO (meat pieces) and modified ISO (centrifuged chicken rinse solution) methods for the detection of Campylobacter spp. Copyright ©, International Association for Food Protection.
