(AP) — Federal officials are offering food safety recommendations to Nebraska residents who may be affected by flooding on the South Platte River.

The Department of Agriculture said in a news release Friday that potential power outages could compromise the safety of stored food and increase the risk of foodborne illness.

Tips for keeping food fresh during a power outage include grouping it together in the freezer to keep it cold longer. Residents should also keep refrigerator and freezer doors closed as much as possible.

The agency’s Food Safety and Inspection Service also says an online publication and YouTube video has instructions on keeping frozen and refrigerated food safe. Information will also be available on two Twitter feeds.
