This study investigated the effectiveness of carrageenan/chitosan coating in combination with allyl isothiocyanate (AITC) against Salmonella Typhimurium and Campylobacter coli on fresh chicken breasts. High (8-7 log10 CFU/g) and low (6-5 log10 CFU/g) inoculation levels represented extreme and average contamination, respectively. When used in combination with the coating, treatment with 200μg/mL AITC reduced (P ≤ 0.05) S. Typhimurium populations by 1.11 and 1.79 log10 CFU/g in the high and low inoculation samples, respectively, after 21 days of storage at 4°C. Populations of C. coli were reduced (P ≤ 0.05) below the detection limit (0.3 log10 CFU/g) in the high and low inoculation samples treated with the coating and 20μg/mL of AITC after 21 days of storage at 4°C. S. Typhimurium exposed to 200μg/mL AITC showed increased (P ≤ 0.05) resistance to AITC after the 21-day exposure period; no change (P > 0.05...
