EMP swabbing

EMP swabbing

What is EMP swabbing

  • An EMP (Environmental Monitoring Program) typically involves routine swabbing of surfaces (e.g. cutting boards, drains, equipment) to test for pathogens (Listeria, Salmonella, etc.) as part of a food safety assurance program.

1. Food Manufacturing & Processing Facilities

  • Bakeries, dairies, meat processors, beverage plants, frozen food producers

  • EMP swabbing is standard to detect Listeria, Salmonella, E. coli in drains, floors, and food contact surfaces.

  • Required by FDA (21 CFR part 117 – Preventive Controls for Human Food) and USDA FSIS (for meat & poultry plants).


2. Retail Food Stores with On-Site Prep

  • Grocery stores with delis, salad bars, bakeries, sushi counters, juice bars

  • Any place where ready-to-eat foods are handled is higher risk → swabbing may be required internally, especially if they seek SQF/BRC/ISO certification.

  • Examples: Whole Foods, Sprouts, large supermarket chains with in-house kitchens.


3. High-Risk Food Retailers

  • Stores selling raw or minimally processed foods (raw seafood, meat, unpasteurized juices).

  • Butcher shops, fish markets, specialty ethnic markets with open prep areas.

  • Local health departments may order swabbing if contamination is suspected.


4. Pet Food Stores / Facilities

  • If they manufacture, repackage, or sell raw pet food → EMP swabbing is often required (FDA and AAFCO guidelines).


5. Distribution & Cold Storage Facilities

  • Warehouses and distribution centers that handle RTE (ready-to-eat) foods may swab for Listeria in cold rooms and loading docks.

  • Often required for third-party audits (SQF, BRCGS, FSSC 22000).


6. Restaurants & Foodservice in Large Chains

  • While not every restaurant in LA is required, fast food chains, ghost kitchens, and corporate foodservice (airports, hospitals, schools) often swab to comply with corporate food safety programs.
