The objective of this study was to evaluate the viability of Campylobacter jejuni and quantify indicator microorganisms (mesophilic bacteria, total coliforms and E. coli) in initial and final broiler feed artificially contaminated with 103 and 105 CFU of C. jejuni per gram of ration, kept at two different temperatures of storage (25 and 370C) and analyzed on four different storage periods 0, 24, 72 and 120 hours. C. jejuni survived throughout the study period and multiplied when inoculated with 103UFC, with the highest counts observed when the feed was kept at a temperature of 370C. Overall, there was a multiplication of mesophilic microorganisms, but the amount of coliforms didn´t increase with time. This work shows that the importance of feed in the epidemiology of C. jejuni in broilers should be better assessed and instigates other studies to verify the possible symbiotic relationship between C. jejuni and mesophilic.
