What must be maintained for partially used ingredient containers?

• A. Expiration date
• B. Supplier contact
• C. Color coding
• D. Ingredient identification and lot number/traceability

Answer: (D)

Maintaining precise identification and traceability for partially used ingredient containers is essential. When an ingredient is opened or partially used, you must still know exactly what it is and which production batch it came from. This allows you to trace any quality issues or recalls to a specific lot, verify that the correct ingredient is used in a product, and manage allergen controls and shelf life accurately.

Ingredient identification means clearly labeling what the item is, along with its supplier or lot information. The lot number ties that container to a specific production batch, date, and quality records, so you can pinpoint the source if a problem arises and determine which products might be affected.

While expiration dates and supplier contact details are useful, they don’t provide the necessary linkage to a specific batch or allow tracing back through the production chain. Color coding is a quick visual aid but does not replace formal identification and traceability.

So, the requirement focuses on keeping both ingredient identification and lot number/traceability for partially used containers.
