Cockroaches are an unwanted sight in a restaurant, but there's a better chance that improper food heating, cooling and storage methods will make diners sick.
Research into which food safety rules are most linked to foodborne illness is giving Twin Cities restaurant inspectors new tools to target unsafe kitchen activities that put customers particularly at risk. Inspectors for Minneapolis and St. Paul found more than 4,800 such violations at about 1,500 restaurants last year, according to a Star Tribune analysis.
"Each time you have one of these, that's like buying a … ticket to the foodborne illness lottery," said Dan Huff, environmental health director for the city of Minneapolis.
The foodborne illness risk factors, outlined by the Food and Drug Administration and the Centers for Disease Control, are a smaller subset of rules than those deemed "critical" under the state's food code. They center on inadequate cooking, food kept at the wrong temperatures, dirty equipment, food from unsafe sources and poor personal hygiene.
Minneapolis has recently begun analyzing those violations more closely, hoping to give them priority in determining which restaurants need extra attention. The Minnesota Department of Health is also crafting updates to the state's food code that would give the most weight to violations that could lead to illness.
Not having a plumbing device that prevents a sink from sucking up dirty water is a critical violation, for example, but it is not considered a top risk factor for illness. Cooling a vat of hot soup too slowly, however, is both a critical violation and a foodborne illness risk since it can lead to bacteria growth that sickens customers. The new approach would prioritize the soup temperature over the sink.
Tougher inspections
Minneapolis' analysis comes after the city revamped its food inspections in the wake of a poor 2010 state audit. It now has eight more inspectors who speak a multitude of languages and spend more time on educating restaurant employees. A re-evaluation from the state this winter resulted in perfect or near-perfect grades.
"We got a lot better as inspectors, which means we got a lot stricter," Huff said.
