A viral Facebook post by the family of a former server at South Haven’s Su Casa Restaurant has prompted a Van Buren County Health Department investigation. The post accused the restaurant of re-serving food that wasn’t eaten by other customers, including chips and salsa. Restaurant owner Edgar Suarez tells Kalamazoo’s WWMT-TV he didn’t know that wasn’t legal, and they’re no longer doing it. The health department is still investigating, and has issued a citation to the restaurant. The Facebook post by Kristie Bowie has been shared nearly 2,800 times.
