Final answer:
The statement about cold food safety is false; cold food should not be left out for more than two hours, whereafter it could become unsafe due to bacterial growth.
Step-by-step explanation:
The statement that cold food should be sold, served, or thrown out within 6 hours of being taken from refrigeration at 41°F (5°C) or lower is false. Perishable foods, including cold foods, should not be left out at room temperature for more than two hours. Cold food must be maintained at 41°F (5°C) or below to prevent bacterial growth. If a cold food has been left out at temperatures above 41°F for more than two hours, it may become unsafe to eat due to potential rapid bacterial growth, which significantly increases between 40 and 140°F (4 and 60°C).
