Excerpts: In 2010, the U.S. Food and Drug Administration (FDA) implemented an egg safety rule to control Salmonella Enteritidis on U.S. farms with 3,000 or more birds that produce eggs for human Consumption. The FDA used information from the USDA’s National Animal Health Monitoring System (NAHMS) Layers ‘99 study while assessing the need for and economic impact of the egg safety rule. As practices on table-egg farms have changed substantially since 1999, it was determined that updated information would be useful to the poultry industry and government agencies. As a result, in summer 2013 NAHMS conducted the Layers 2013 study to describe current management practices on U.S. table-egg farms and, in particular, management practices relevant to controlling S. Enteritidis. The 1999 study sample was selected from the USDA’s National Agricultural Statistics Service’s list of table-egg operations with 30,000 or more hens in 15 States. The 2013 study sample was selected from the FDA list of all registered egg producers with 3,000 or more laying hens in 19 States; a subset of farms with 30,000 or more hens was used for comparison to the 1999 study. Results from the two studies are highlighted in this document.
