When holding food in a buffet table you should avoid?

When holding food on a buffet table, you should avoid leaving perishable items out for more than two hours to prevent bacterial growth. It's also important to avoid cross-contamination by using separate utensils for different dishes. Additionally, ensure that hot foods are kept at a temperature of at least 140°F and cold foods at or below 40°F to maintain food safety. Lastly, refrain from using decorative items that could introduce contaminants to the food.
