Dr. Shuster says the other major concern is the dishtowel. Cross contamination can be eliminated if people don't use dishtowels to dry their hands and wipe off counters. Meat can be far more dangerous than vegetables but its equally important to rinse off both. It gets dangerous when you cross-contaminate to fresh foods that you don't cook. People tend to prepare first, then vegetables, we recommend that people prepare vegetables first then go to the meat then you don't have the problem of cross contamination.
Most people just check their meat by cutting it and looking at the color.
The color of the meat is not an indication of doneness. It can look done but might not be. It was amazing to see so many people use dishtowels, a lot of people don't want to use paper towels because they think its wasteful but its really an important tip. You Can Afford. Always Well Done.
