The objective of this study was to determine the efficacy of 16 active compounds and 11 commercial disinfectants against Campylobacter jejuni. Two reference strains (one of avian origin and the other isolated from bovine) and two avian field strains were tested in suspension test in the presence and absence of serum. Chloramine-T, povidone-iodine (1% available iodine), cetylpiridinium chloride, ethanol, isopropanol, chlorhexidine digluconate, formaldehyde, phenol, and 10 of the 11 commercial formulations (eight of them based on quaternary ammonium compounds) showed an excellent disinfectant capability, resulting in the highest level of reduction (>6-log(10)) in colony-forming units of the four C. jejuni strains compared regardless of the presence or absence of organic material. These compounds might be helpful in the adoption of environmental control measures against C. jejuni.
