Step-by-step explanation:
The government agency responsible for monitoring the cleanliness of food and ensuring that no food-borne illnesses arise is the Food and Drug Administration (FDA). The FDA, an agency within the United States Department of Health and Human Services, enforces laws to ensure the purity, effectiveness, and truthful labeling of food, among other responsibilities. Moreover, the FDA works closely with other federal agencies, such as the United States Department of Agriculture (USDA), to conduct routine bacteriological testing to protect the public from foodborne diseases.
Concerning the three main ways food can become contaminated, they include poor hygiene, cross-contamination, and failure of temperature control. Some basic food safety practices to prevent the transmission of foodborne disease in the home are regular handwashing, avoiding cross-contamination, and maintaining correct refrigerator temperatures.
