Two Grosse Pointe restaurants have voluntarily shut while the Wayne County Health Department investigates multiple cases of Hepatitis A suspected of being related to the establishments, WWJ reports.

The restaurants, Uncle Paul’s Pizza, 21215 Mack Ave., Grosse Pointe Woods and the Cabbage Patch Café & Catering, 15110 Kercheval Ave., Grosse Pointe Park, are cooperating.

Anyone who ate there between Aug. 1 and Sept. 29 should watch for abdominal pain, nausea, vomiting, diarrhea, dark urine, clay colored stool, fever and chills, along with yellow skin and eyes (jaundice). Symptoms occur 15 to 50 days after exposure and can last several weeks or even months.

Hepatitis A is a vaccine-preventable disease.
