Mobile Merchandiser Health and Sanitation Practices
6
Health and Sanitation Practices
BKI ovens are manufactured to comply with health regulations and are tested and certified to UL, CUL, and
NSFstandards. You must operate the equipment properly using only quality products and use meat
thermometers to insure meats are thoroughly cooked.
Food Handling
•Wash hands thoroughly in warm, soapy water after handling raw poultry or meats.
•Clean and sanitize all utensils and surfaces that have been in contact with raw products.
•Never place cooked meats on the same surfaces used to prepare raw meats, unless the area has been
thoroughly cleaned and sanitized.
Storage of Raw Meats
•Designate an area or shelf strictly for the storage of all raw meats to be used in the oven.
•Raw product must always be stored at temperatures below 38° F. (3° C.).
•Never store or mix raw foods above cooked foods, as this is a health hazard. The drippings from raw
foods contaminate cooked or processed foods.
•All chicken and chicken parts to be stored overnight must be thoroughly iced down and refrigerated.
Coding Cooked Foods
All products cooked during the day should be sold the same day.
NOTE: It is not the intent of the cooking program to have unsold merchandise at the end of the cooking day.
Follow your company’s procedures for the handling of any leftover product.
Storage of Prepared Foods
•Cold foods should be kept at or below 38° F. (3° C.).
•Hot foods must be maintained to meet local health codes, usually a minimum 145° F. (63° C.).

Temperature Adjustment
After loading the unit with product, it may be necessary to adjust the temperature control knob in order to
maintain the proper internal temperature for the product on display. The temperature control knob should
be set to the lowest possible number that will maintain the proper product temperature.
Operational Guidelines
•Food internal temperature should be a minimum of 175F [80C] when being placed in the unit.
•Foods loaded in first should be served first as much as is practical.
•Check Federal and State Health and Sanitation Regulations for internal temperature required for
holding cooked foods for sale. Maintaining these temperatures often tends to continue to cook
certain products. Therefore, smaller amounts of bulk foods should be displayed at non-peak
periods and the warmer refilled as needed.
This equipment is designed to hold foods for a short period of time only.
