Health officials in the Netherlands are after food germs and bacteria in a big way these days. They are placing large posters with wording made of actual food germs all over the country. The text on these posters give tips to avoid food poisoning such using a different cutting board for meat and vegetables, what temperature at which to set your refrigerator, how hot foods such get before eating. Also, stir your food you heat up in the microwave.
It's kind of gross when you think about letters made from actual food bacteria, but it seems to be working. I wonder how big a problem food poisoning must be in the Netherlands.
