Question

which is a condition that should be considered when purchasing food that is safe?
fruits should not be prewashed.
the sell - by date should not be expired.
products should not have a nutritional label.
meat should be in a package that allows for air circulation.

Explanation:

• Fruits can be prewashed, so "Fruits should not be prewashed" is incorrect.
• Products should have a nutritional label for consumers to know about the product, so "Products should not have a nutritional label" is wrong.
• Meat should be in a package that is sealed (to prevent contamination), not one that allows for air circulation. So "Meat should be in a package that allows for air circulation" is incorrect.
• The sell - by date indicates the time until which the product is considered at its best quality and safe (in most cases). If the sell - by date is expired, the food may have started to deteriorate or be unsafe.

Answer:

The sell - by date should not be expired.
