All through the year I get many questions about safely entertaining. While cooking ahead and buffet serving is a traditional way of serving large groups, it is essential that food safety guidelines are followed. The USDA Meat and Poultry Hotline (888-674-6854) is available from 10 to 4 on weekdays  to answer your questions and offers on-line help 24/7. Other US Government sites have helpful information as well; go to foodsafety.gov.
