an ounce of prevention write an x next to the practice if it helps prevent cross - contamination.
1____use separate cutting boards for prepping raw meat and raw vegetables.
2____wash and rinse a cutting board after prepping raw fish.
3____buy diced onions instead of dicing them in the operation.
4____prep salads before prepping raw meat on the same prep table.
5____use green - handled knives to prep produce and yellow - handled knives to prep raw poultry.
6____wipe down prep tables with a wiping cloth between different tasks.
7____cook chicken in - house instead of buying precooked chicken.

Explanation:

• 1. Use separate cutting boards for prepping raw meat and raw vegetables: Raw meat can carry harmful bacteria. Using separate cutting boards prevents bacteria from raw meat from contaminating raw vegetables (which are often eaten raw).
• 2. Wash and rinse a cutting board after prepping raw fish: Raw fish can have bacteria. Washing the cutting board removes these bacteria, preventing them from contaminating other foods.
• 4. Prep salads before prepping raw meat on the same prep table: Salads are often eaten raw. Prepping them first (before raw meat which can contaminate) reduces the risk of cross - contamination.
• 5. Use green - handled knives to prep produce and yellow - handled knives to prep raw poultry: Using different knives for different food types (produce vs. raw poultry) prevents bacteria transfer.
• 6. Wipe down prep tables with a wiping cloth between different tasks: This removes any bacteria or contaminants from one task (e.g., raw meat) before starting another task (e.g., ready - to - eat food).

• 3. Buy diced onions instead of dicing them in the operation: This has no direct relation to cross - contamination prevention. It may be a convenience measure but does not address the transfer of bacteria between foods.
• 7. Cook chicken in - house instead of buying precooked chicken: This is more about food quality, cost, or freshness control rather than cross - contamination prevention. Cross - contamination prevention would focus on handling (e.g., separating raw and cooked, proper storage during cooking etc.), not on the decision to cook in - house.
