What must proper labeling and invoices identify?

• A. What the food is and where it came from
• B. The supplier's contact number
• C. The price per unit
• D. The packaging color

Answer: (A)

The key idea is traceability—knowing exactly what the item is and where it came from. Proper labeling should clearly state the product identity so you know what the item is (for example, the exact food item) and its source or supplier, which helps with correct handling, storage, and allergen awareness. Invoices provide the paper trail that confirms who supplied the item and what was purchased, supporting recalls and supplier verification. Details like a supplier’s contact number, price per unit, or the packaging color aren’t essential for identifying the product or its origin, so they aren’t essential parts of labeling and invoice identification.
