PAR-20-105: Discipline D – Special Projects - Track 3: Method Validation Project Summary The Washington State Department of Agriculture (WSDA) Food Safety and Consumer Services (FS&CS) Laboratory is the State’s Primary Regulatory Human Food and Animal Feed Safety Laboratory. We seek 5 years of funding through the FDA Laboratory Flexible Funding Model (LFFM) Cooperative Agreement Program’s Discipline D Special Projects Track 3, Method Development and Validation. We plan to utilize the funding to conduct preliminary, short-term or exploratory investigations that focus on the feasibility of a new method and/or technology. We propose to be part of the multi-laboratory validation of a qPCR screening method for Salmonella in foods in Year-1.  The FS&CS Laboratory has two decades of recent work developing new methods and validating the methods. From 2001-2013 the laboratory was one of 8 selected state agriculture laboratories for support under the USDA Microbiological Data Program. The purpose of this program was to develop and validate testing methods for fresh produce. Another purpose was to understand the frequency of detected pathogens in various produce items.  The Laboratory has extensive experience working with complicated matrices that present challenges to modern technical testing platforms. For instance, sprouts are difficult to test since there is a lot of interference with real-time PCR.  Each method for Salmonella, Listeria, E.coli O157:H7, non-O157 E.coli (STEC), Shigella had to be adapted to testing produce. This required years of work to discover, verify and validate the methods. Each matrix then had to be re-verified and validated.  The Laboratory has worked under the FDA FERN MCAP for over 10 years. A primary goal of this cooperative agreement is to develop testing methods on newer test platforms and then validate those methods. In addition, we have a long history of collaborating with private companies who manufacture test kits and analytical equipment, in order to get some of these technologies approved by AOAC and available for our commercial use.  The Laboratory utilizes the FDA Guideline for the Validation of Analytical Methods. If our Track 3 proposal is accepted, we are willing and able to do the following: 1. Participate the multi-laboratory validation of a qPCR screening method for Salmonella in foods by following FDA guidelines for method validation.

PAR-20-105：学科D - 特殊项目 - 轨道3：方法验证 项目摘要 华盛顿州农业部（WSDA）食品安全和消费者服务 （FS＆C）实验室是该州的主要监管人类食品和动物饲料安全 实验室。我们通过FDA实验室灵活资助模型（LFFM）寻求5年的资金 合作协议计划的纪律d特殊项目轨道3，方法开发和 验证。我们计划利用资金进行初步，短期或探索性 调查着眼于新方法和/或技术的可行性。我们建议参与 1年级食品中沙门氏菌的QPCR筛选方法的多实验性验证。 FS＆CS实验室有二十年的最近开发新方法和验证的工作 方法。从2001 - 2013年开始，实验室是8个选定的国家农业实验室之一 在USDA微生物数据计划下进行支持。该程序的目的是 开发和验证新鲜农产品的测试方法。另一个目的是了解 各种生产项目中检测到的病原体的频率。 实验室拥有丰富的经验 现代技术测试平台的挑战。例如，豆芽很难测试，因为 实时PCR有很多干扰。 沙门氏菌，李斯特菌的每种方法 适应测试产品。这需要多年的工作才能发现，验证和验证 方法。然后，每个矩阵必须重新验证和验证。 实验室在FDA FERN MCAP下工作了10多年。这是这个的主要目标 合作协议是在较新的测试平台上开发测试方法，然后验证 这些方法。此外，我们与私营公司合作的历史悠久 制造测试套件和分析设备，以获取其中一些技术 经AOAC批准，可用于我们的商业用途。 实验室利用FDA指南来验证分析方法。 如果我们的曲目3提案被接受，我们愿意并且能够做以下操作： 1。参与食品沙门氏菌的QPCR筛选方法的多样性验证 通过遵循FDA验证指南。 华盛顿州农业，食品安全和消费服务实验室
