Get 7 tips from local Chefs on how to prevent cross-contamination in food.

Food cross-contamination is known as the transfer of bacteria or other microorganisms from one substance to another. Cross contamination can also occur in allergens, chemicals and toxins. Cross Contamination in food can occur in the following 3 ways:

  • Food to Food
  • People to Food
  • Equipment to Food
The below tips will help you prevent cross contamination and prevent food-born illnesses among your guests:

Check the delivery temperature

When fresh produce is delivered, measure the temperature of each ingredient. If the temperature is not correctly chilled, bacteria can grow faster, leading to the birth of food-borne illnesses. If this is the case, call your delivery partner immediately and return the produce.

Keep Toxic Chemicals away from Food

Keep toxic chemicals and cleaning products away from food. Never put hazardous substances above food.

Floor Level storage is a no-go

Do not store boxes on the floor, but on a raised platform or shelf. The floor is a source of bacteria. All foods in a commercial kitchen must be stored at least 6 inches above the floor.

A well looked after Storage Space goes a long way

Make sure the storage space and products are clean and hygienic. You should be able to close the storage area to keep it dry and safe from pests.

Use the FIFO system

FIFO stands for First-In First-Out. It is a system for facilitating stock storage. Products with the earliest best before date should be placed at the front of the storage area, whereas products with the furthest dates can be kept at the back. In using a FIFO food storage system, you ensure that food with the soonest BB dates are used first. This system maximizes freshness and minimizes waste.

Stick it with a Label

When food is prepared, remember to add preparation date to dish. It's best if you use stickers here with components such as date, dish name, date of prep.

By keeping these categories in mind, you can design an upselling strategy that will bring in additional revenue while improving customer satisfaction levels.
