Contamination on the exterior surfaces of raw poultry packages can be transmitted to hands and food contact surfaces during shopping and handling. This study compared the level of microbial contamination and prevalence of foodborne pathogens on the surfaces of raw poultry packages as related to the types of products, types of packaging, and packaging conditions. Packages of whole chicken, cut-up chicken (breast and leg quarter), and ground turkey were purchased from retail stores. Aerobic plate counts (APCs) were significantly different (P < 0.05) among types of products and packaging materials, with ground turkey packages and the heat-sealed, high-walled containers being the lowest. APCs were significantly lower (P < 0.05) when the packages were intact and tight compared with intact and loose. Of the 105 packages, there were 10 (9.5%) with the presence of either Shiga toxin–producing Escherichia coli (STEC) or Campylobacter; of those packages, 6 (5.7%) were positive for STEC, 7 (6.7%) were positive for Campylobacter, and 3 (2.9%) were positive for both pathogens on the surfaces. Salmonella was not detected on the surfaces of all tested packages. Surfaces of whole chicken packages were significantly (P < 0.001) more likely to have detectable levels of Campylobacter and STEC than those of cut-up chicken packages. Packages that were positive for Campylobacter and/or STEC had significantly (P < 0.005) higher APCs than negative packages. The results suggested that STEC is another significant pathogen present on the surfaces of poultry packages in addition to Campylobacter. The presence of STEC on the external packaging of raw poultry raises a concern because consumers may not expect such pathogens on the surfaces of poultry packages.
