According to the AP, new research suggests that "at least one in seven home kitchens would flunk the kind of health inspection commonly administered to restaurants." Among questions in the study, people were asked "whether raw meat is stored below other foods on refrigerator shelves, and whether fruits and vegetables are always thoroughly rinsed before they are eaten."
This new finding certainly doesn't surprise me. I've been in plenty of kitchens that look straight out of Animal House, and I'll admit that I probably use the wrong sponge for washing dishes from time to time.
So I'd give my kitchen a B (some weeks B-) in the cleanliness department. How about you?
