Food Safety and Inspection Service (United States Department of Agriculture).
In calendar year 2014, the Food Safety and Inspection Service (FSIS, part of the United States Department of Agriculture (USDA), analyzed 18,087 verification samples across three meat and poultry product classes with the following rates of Salmonellapositives by product class: young chicken ( 3.8%), ground beef (1.6%) and turkey (1.7%). FSIS believes that the higher the percent positive rate, the greater the potential for the public to consume a product that can cause foodborne illness. FSIS scheduled approximately 75 sample sets monthly using a risk-based algorithm to target establishments demonstrating variable or poor process control (i.e., establishments with high percent positive rates). Previous Salmonella Annual Reports can be found on the FSIS web site.
