zmey [24]

Here are five suggestions for preventing food contamination so that you and your family can reduce your chance of getting sick.

1) Wash your hands first.

2) Constantly look for Use-By dates.

3. Clean Cutting Boards and Work Areas

4) Take Good Care of Your Fridge.

5) Ensure that your food is well cooked.

<h3>What are ways to prevent food contamination?</h3>
  • Food service workers should clean and disinfect surfaces, tools, and utensils after using them with different meals, especially after handling raw meat.
  • Foods that are ready to eat should be kept on the upper shelves of the refrigerator.
  • By doing this, the cooked meal will not become contaminated by the juice from raw items that would otherwise drip down.
<h3>How may pathogens be prevented from entering food?</h3>
  • Frequent hand and surface washing.
  • Wash your hands with soap and hot water both before and after handling food, using the restroom, changing diapers, or petting animals.
  • Use paper towels or clean cloths combined with hot, soapy water to clean spills or kitchen surfaces.
<h3>In what ways is food contamination avoided?</h3>

Frequent hand- and surface-washing. Cutting boards, cutlery, and counter tops in the kitchen can all become contaminated with dangerous bacteria. Wash your hands with soap and hot water before and after handling food, going to the bathroom, changing diapers, or touching pets in order to avoid this.
