Howard County health officials are warning residents that they have had several reports of unlicensed vendors selling packaged frozen food from freezers strapped into the back of pick-up trucks.

The county Health Department warned that there is no guarantee the food has been kept at proper temperatures, or is safe to eat.

Dr. Peter Beilenson, county health officer, advised buying only from licensed, regulated food establishments.

Anyone with questions may call the Bureau of Environmental Health at 410-313-1772.
