The National Registry of Food Safety Professionals states that you can take an online certificate test for a food handler online at any time via its official website. The program is accredited by the American National Standards Institute and the American Society for Testing and Materials.
During this course, the National Registry of Food Safety Professionals states that individuals will learn techniques in personal hygiene, cleaning and sanitizing, handling pests, how to identify potentially hazardous foods and about time temperature control. An introduction to food safety, contamination and cross contamination is also covered. The certificate is valid for up to five years depending on the state laws where a food handler works.
