The results are based not on actual inspections,but on an Internet quiz taken by about 13,000 adults.So it's hard to use it to compare the conditions in home kitchens to those in restaurants,which involve trained inspectors giving objective assessments of dirt,pests,and food storage and handling practices.
What's more,experts don't believe that study is representative of all households,because people who are more conscientious about food safety are more likely to take the quiz.
“You'll miss a big population who don't have home computers or just really don't care about the cleanliness of their kitchens,”said Martin Bucknavage,a food safety specialist with Penn State University's Department of Food Science.
A more comprehensive look would probably find that an even smaller percentage of home kitchens would do well in a restaurant inspection,he suggested.
In 2006,the county health department began a home kitchen selfinspection program,designed to help consumers learn how to store and prepare food safely.The department also began offering an online quiz with 45 yes or no questions that simulates(模仿)a restaurant inspection checklist.
People are asked,for example,if their refrigerator temperature is 41 degrees Fahrenheit or lower,whether raw meat is stored below other foods on refrigerator shelves,and whether fruits and vegetables are always thoroughly rinsed before they are eaten.
