Salmonella enteritidis


June 28, 2010

Federal regulations require most egg producers to take steps to prevent the spread of Salmonella enteritidis

On July 9, 2010, FDA new Final Rule titled “Prevention of Salmonella enteritidis in Shell Eggs During Production, Storage, and Transportation” went into effect. The regulation requires preventive measures during the production of eggs in poultry houses and requires subsequent refrigeration during storage and transportation. The rule requires that measures designed to prevent Salmonella enteritidis be adopted by virtually all egg producers with 3,000 or more laying hens whose shell eggs are not processed with a treatment, such as pasteurization, to ensure their safety.

To comply with the new federal requirements, most egg producers must do the following:

  • Have and implement a written Salmonella enteritidis prevention plan and document compliance.
  • Buy only pullets tested for Salmonella enteritidis contamination or raise pullets under monitored conditions.
  • Implement biosecurity and pest control programs.
  • Clean and disinfect poultry houses with positive Salmonella enteritidis test results.
  • Refrigerate eggs at 45° F (9.44° C) during storage and transportation.
  • Conduct environmental tests for Salmonella enteritidis and test eggs following positive environmental tests.
  • Keep records related to flocks for one year after the flocks are permanently taken out of production.
  • Make records available to the FDA within 24 hours of an official request.
  • Producers must register with the FDA, which the Federal Register notice states will help the agency with annual inspections and resource allocation.

Producers with more than 50,000 laying hens need to comply with the rule by July 9, 2010, and those with more than 3,000 laying hens but fewer than 50,000 must comply by July 2012.
