Research Project: Identification of actionable sentinels for Salmonella contamination of lymph nodes and determining the impact of environmental contamination levels.

Location: Meat Safety and Quality

Project Number: 3040-42000-021-006-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Jul 1, 2021
End Date: Jan 1, 2023

Objective:
The goal of this study is to identify actionable measures the beef industry can implement to reduce the risk of Salmonella in ground beef.

Approach:
Identify feedlots with high and low levels of high risk Salmonella and determine their impact through processing including lymph nodes on risk of Salmonella contamination. Sample hides, carcasses and lymph nodes and measure prevalence, levels, virulence and serotypes of Salmonella. Sample mesenteric lymph nodes, trim and ground beef for prevalence, levels, virulence and serotypes of Salmonella from 2 processing plants.
