Final answer:
Reject food deliveries if hot foods aren't kept hot or cold foods aren't kept cold, if perishable items have been in the danger zone temperature for over two hours, or if there are signs of spoilage. These preventative measures are crucial to avoid foodborne illness.
Step-by-step explanation:
You should reject food from deliveries when it doesn't meet specific safety criteria to ensure the health of the digestive system. Reject food if it's been held at unsafe temperatures, that is hot foods that are not kept hot (above 140 degrees F) or cold foods that are not kept cold (below 40 degrees F). Also, if the packaging is compromised, or if perishable foods have been at a temperature between 4 and 60 degrees C (40 and 140 degrees F) for more than two hours, this could also lead to foodborne illness. Always check for signs of spoilage, such as off-odors or colors. Proper handling, such as regular handwashing and using a cooking thermometer, can prevent the spread of bacteria responsible for foodborne diseases.
