Authorities in Bosnia’s capital have declared a food poisoning epidemic after nearly 200 preschool children became sick at public day care centers in Sarajevo.

Local health minister Emira Tanovic-Mikulec declared the epidemic on Monday.

Lab tests show that the food the children ate last week was infected with Salmonella enteridis.

About 2,900 kids eat food prepared in a central kitchen that supplies the 29 centers in Sarajevo.

The symptoms started last Wednesday when macaroni with cheese and eggs was on the menu.
