The state secretary of agriculture is warning restaurant owners, managers and staff of a potential scam.

A caller claims to be a health inspector and asks for business information and money, Agriculture Secretary George Grieg said in a news release.

Similar incidents were reported in 2011.

He reminded restaurants that inspections by the Department of Agriculture inspectors are always unannounced. Upon arrival, inspectors will identify themselves and show proper identification, including a commonwealth employee photo identification card and food sanitarian badge

If a restaurant is contacted by someone claiming to be a health inspector who seems suspicious, restaurant personnel should contact local law enforcement.
