Meals from a Los Angeles charity are suspected of causing 32 cases of salmonella at preschools, hospitalizing at least 10 children and five adults.

Bob Pratt, president of Volunteers of America Greater Los Angeles, said Thursday the problem is under control and operations have resumed at the charity's North Hollywood kitchen. The charity, which provides meals for several Headstart programs, began getting reports of salmonella on Oct. 15 from preschools in the San Fernando Valley and East Los Angeles.

Los Angeles County health officials say 28 of the centers reported cases.

The County Department of Public Health ordered the charity to throw out all food and wash down the facility with a bleach-and-water solution.

County health director Jonathan Fielding says the cause of the salmonella is under investigation.
