MILWAUKEE (CBS 58) -- Cermak Fresh Market stores in Milwaukee are putting in thermal scanners to check the temperatures of people who come through the door. A fever is one symptom of coronavirus. 

If the scanner detects someone with a temperature of 100.4 degrees or higher, the store manager hears an alarm. 

Then the customer is tested a second time. 

"After that second reading, if it's still high, we're gonna use a hand held device...on the forehead. Once that works out, if it is high still then at that point, we would ask the customer to leave," said Joe Marano, store manager. 

The scanners are Cermak's attempt to keep other customers and employees safe from the virus.
