Shipping Instructions:

  • Ship all foods in containers with hard walls and lids secured in the closed position.
  • Shipping containers must be labelled with the submitting organization, unique identifier and contents e.g. FOOD SAMPLES on the outside of the container.
  • DO NOT SHIP WITH CLINICAL SPECIMENS.  Shipping containers used for food samples should be dedicated to food samples and not be used for other types of environmental samples.
  • Ship dry foods and other shelf stable foods in a closed container at ambient temperature.
  • Ship frozen foods in an insulated container with sufficient ice packs to maintain the frozen state.

  • Submit all food samples to the laboratory as soon as possible

​The presence of Salmonella spp. in food is screened by real time polymerase chain reaction (RT-PCR).  All RT- PCR positive samples will be confirmed by culture techniques including nonselective pre-enrichment, selective enrichment followed by isolation on selective agar plates, biochemical and serological identification.

Salmonella spp. should be absent from ready-to-eat foods.
