The Agricultural Marketing Service (AMS) purchases cooked diced chicken, pasteurized liquid whole eggs, and pasteurized dried egg mix for federal nutrition assistance programs. Purchases are made from establishments that have met the financial and technical requirements to become AMS-approved vendors. Cooked diced chicken is tested for the presence of and , and for levels of aerobic plate count (APC) organisms, coliforms, and generic (GEC). Of 3668 samples collected from October 2012 through September 2018, none were positive for , 3 (0.8%) were positive for , 8 (0.22%) exceeded the APC critical limit (CL) of 1000 colony-forming units (CFUs)/mL, 15 (0.41%) exceeded the coliform CL of 50 CFU/mL, and 5 (0.14%) exceeded the GEC CL of 10 CFU/mL. Pasteurized liquid whole egg and pasteurized dried egg mix are tested for the presence of and for levels of APC and CL. Of 984 pasteurized liquid whole egg samples collected from October 2012 through September 2018, 1 (0.10%) was positive for , 29 (2.5%) exceeded the APC CL, and 4 (0.41%) exceeded the coliform CL. Of 380 pasteurized dried egg mix samples collected during this period, none was positive for , none exceeded the APC CL, and 3 (0.79%) exceeded the coliform CL. All production lots from which samples found to contain pathogens or to exceed indicator organism CLs were identified and rejected for purchase by AMS. These data suggest that cooked diced chicken and pasteurized egg products produced for federal nutrition assistance programs are done so under effective food safety systems.
美国农业部的农产品市场服务局（AMS）为联邦营养援助计划购买煮好的切丁鸡肉、巴氏消毒液态全蛋和巴氏消毒干蛋混合物。这些采购都来自那些符合财务和技术要求的机构，使其成为 AMS 认可的供应商。煮好的切丁鸡肉要检测沙门氏菌和志贺氏菌的存在情况以及需氧平板计数（APC）、大肠菌群和一般肠球菌（GEC）的水平。在 2012 年 10 月至 2018 年 9 月期间采集的 3668 个样本中，没有一个样本对沙门氏菌和志贺氏菌呈阳性，3 个样本（0.8%）对志贺氏菌呈阳性，8 个样本（0.22%）超过了 APC 关键限量（CL）的 1000 个菌落形成单位（CFU）/mL，15 个样本（0.41%）超过了大肠菌群 CL 的 50 CFU/mL，5 个样本（0.14%）超过了 GEC CL 的 10 CFU/mL。巴氏消毒液态全蛋和巴氏消毒干蛋混合物要检测沙门氏菌和志贺氏菌的存在情况以及 APC 和 CL 的水平。在 2012 年 10 月至 2018 年 9 月期间采集的 984 个巴氏消毒液态全蛋样本中，有 1 个样本（0.10%）对沙门氏菌呈阳性，29 个样本（2.5%）超过了 APC CL，4 个样本（0.41%）超过了大肠菌群 CL。在这期间采集的 380 个巴氏消毒干蛋混合物样本中，没有一个样本对沙门氏菌呈阳性，没有一个样本超过 APC CL，有 3 个样本（0.79%）超过了大肠菌群 CL。所有发现含有病原体或超过指示菌 CL 的样本的生产批次都被确定，并被 AMS 拒绝购买。这些数据表明，为联邦营养援助计划生产的煮好的切丁鸡肉和巴氏消毒蛋制品是在有效的食品安全体系下生产的。
