Raw poultry products often are contaminated with Salmonella and Campylobacter, and these bacteria can be transmitted through meat juice on the packages. An observational study was conducted to assess consumer exposure to meat juice during shopping and to quantify the transmission of meat juice from poultry packages to hands and other surfaces. Ninety-six participants completed the shopping study; 402 swabs were collected and analyzed for the presence of meat juice by an immunoassay. Overall, meat juice was detected on 61% of poultry package surfaces, 34% of shoppers' hands, 41% of grocery bags, 60% of kitchen surfaces, and 51% of food item surfaces. When meat juice was detected on the purchased poultry packages, the chance of the meat juice being on the shopper's hands, grocery bags, food items, and kitchen surfaces was significantly higher ( P < 0.005) compared with packages on which meat juice was not present. Shoppers who had poultry wrapped separately during checkout had a significantly lower ( P < 0.05) chance of meat juice on the food items. However, using plastic bags and wrapping poultry separately did not significantly reduce the likelihood of meat juice on kitchen surfaces at home due to consumers' practices of repackaging before storage. Results suggested that the transfer of meat juice through direct contact with the poultry packages is a major concern during shopping and should be prevented.
生鲜家禽产品常常被沙门氏菌和弯曲杆菌污染，这些细菌可通过包装上的肉汁传播。开展了一项观察性研究，以评估消费者在购物过程中接触肉汁的情况，并量化肉汁从家禽包装传播到双手和其他表面的情况。96名参与者完成了购物研究；共采集了402份拭子样本，并通过免疫测定法分析是否存在肉汁。总体而言，在家禽包装表面检测到肉汁的比例为61%，在购物者手上为34%，在购物袋上为41%，在厨房表面为60%，在食品表面为51%。当在购买的家禽包装上检测到肉汁时，与未检测到肉汁的包装相比，肉汁出现在购物者手上、购物袋上、食品上和厨房表面的几率显著更高（P<0.005）。在结账时将家禽分开包装的购物者，食品上出现肉汁的几率显著更低（P<0.05）。然而，由于消费者在储存前重新包装的习惯，使用塑料袋和将家禽分开包装并不能显著降低家中厨房表面出现肉汁的可能性。结果表明，在购物过程中，通过直接接触家禽包装而导致肉汁转移是一个主要问题，应予以预防。
