Study: Packed lunches may cause foodborne illness

August 8, 2011

Researchers at the University of Texas tested 700 packed lunches at a daycare center. Findings show as many as 90 percent of lunches reached unsafe temperatures, even when placed in a heated thermal container or in a bag with ice packs.

Experts recommend freezing beverages like water or milk, which will act as an additional ice pack to keep foods colder. They should thaw by lunch time.
