Emergency food shelf life: what the label means

Separate safety dates from quality dates

A use-by date concerns safety. A best-before date concerns quality. Do not eat food after its use-by date, even if it appears normal. Follow storage instructions as well as the date.

Ask about the stock you will receive

An advertised lifespan may be measured from manufacture. Before a large order, ask for the remaining shelf life on delivery, the date-mark format and whether mixed products have different dates. Put any agreed minimum remaining life in the order confirmation.

Choose the storage location carefully

Use the conditions specified by the manufacturer. A loft, vehicle or damp outbuilding may not provide them. Protect packaging from damage and keep labels readable.

• Record product, quantity, batch and date.
• Use the earliest suitable stock first.
• Check periodically for leaks, swelling, damage or pests.
• Keep food separate from chemicals and contamination.

Opening changes the rules

An unopened shelf-life claim does not tell you how long an opened tin or pouch can be kept. Follow the after-opening instructions, including refrigeration requirements. For power-cut planning, consider pack sizes you can finish safely in one sitting.
