Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, whether his Department has made an assessment of the potential merits of updating the international frozen food storage standard from –18°C to –15°C, including the potential impact on (a) energy costs for producers and retailers, (b) efficiencies in the food supply chain and (c) consumer prices; and whether the Government plans to support such a change in international standards.

The Government welcomes new and innovative steps taken by any businesses to produce and supply food sustainably, providing they can demonstrate the food they place on the market is safe.

There is no legal requirement for frozen food to be stored at -18°C in general, but freezing remains a critical control step in some cases, such as killing parasites in fish intended to be eaten raw, and these requirements continue to apply.

We are aware that parts of the food industry are exploring raising frozen food storage temperatures from -18°C to -15°C to reduce energy use and support sustainability goals. While this evidence has not yet been shared with the Food Standards Agency, we are engaging with food businesses to understand potential implications. The Government will continue to monitor industry trials and evidence related to international frozen food storage standards.

Raising frozen food storage temperatures could reduce energy use for food business operators, which may help lower operating costs. At present, there is no clear evidence that such changes would lead to lower prices for consumers.

Any food business considering changes to frozen food storage temperatures must ensure food safety management systems remain compliant with legal requirements.
