U.S. Food Safety Systems
Food Safety: Regulation & Oversight
Food safety in the United States is maintained through the coordinated efforts of multiple governmental agencies, each with specific roles in the food supply chain. Understanding these agencies and their responsibilities is essential for ensuring the safety and quality of food from farm to table.
Environmental Protection Agency (EPA)
Establishes safe levels for pesticides, water, and residue limits.
Regulates environmental contaminants in food production.
Example: Setting maximum residue limits for pesticides on crops.
United States Department of Agriculture (USDA)
Food Safety & Inspection Service (FSIS): Oversees safety and labeling of meat, poultry, and eggs.
Regulates processing and production of animal-derived foods.
Example: Inspecting meat processing plants for contamination.
Food and Drug Administration (FDA)
Regulates safety and labeling of most foods (excluding meat, poultry, and eggs).
Ensures proper labeling and safety of processed foods, dairy, seafood, and produce.
Example: Setting standards for packaged food labeling and safety.
Center for Disease Control and Prevention (CDC)
Monitors and investigates outbreaks of foodborne illness.
Provides public health guidance and education.
Example: Tracking sources of E. coli outbreaks in produce.
Agency | Main Responsibility | Food Chain Stage |
|---|---|---|
EPA | Sets pesticide and contaminant limits | Farm/food origin |
USDA | Inspects meat, poultry, eggs | Processing & production |
FDA | Regulates most other foods | Processing, retail, consumption |
CDC | Monitors outbreaks | Consumption |
Key Point: The FDA is responsible for assuring the safety and quality of most food products, except for meat, poultry, and eggs (USDA).
Food Product Dating
Food product dating labels help consumers determine the freshness and safety of food items. However, not all foods are required to have these labels, and their meanings can vary.
Label Types:
"Sell by" date: Indicates how long a store should display the product. Not a safety date.
"Best if used by/before" date: Refers to the best flavor or quality, not safety.
"Use by" date: Last date recommended for use at peak quality. For infant formula, this is a safety date.
"Expiration" date: Food should not be consumed after this date (mainly for baby formula).
Regulations:
Only baby formula is federally required to have a "use by" date.
Other foods may have dates for quality, not safety.
Signs of Spoilage:
Look for changes in odor, color, texture, or taste.
When in doubt, discard the food.
Example: Hard cheeses like Parmesan can be safe for months past the "sell by" date if properly handled, due to low water content and high acidity, which inhibit microbial growth.
Ensuring Food Safety
Proper food handling and storage are essential for maintaining food safety and preventing foodborne illness.
Consume food before the label date for best quality.
For safety, ensure food has been handled and stored properly, and check for signs of spoilage.
Refrigeration and proper packaging extend shelf life and reduce risk of spoilage.
Example: Meats, dairy, and eggs are required by the FDA to have a "sell by," "safe by," or "use by" date, but canned goods and baby formula have different requirements.

Food safety systems are covered under Chapter 12: Food Safety and Technology: Protecting Our Food.
Understanding the roles of different agencies helps in identifying sources of foodborne illness and regulatory actions.
