U.S. Food Safety Systems: Videos & Practice Problems

Food safety is regulated by multiple federal agencies: the EPA sets pesticide residue limits and water quality standards at the farm level; the USDA’s FSIS inspects meat, poultry, and eggs; the FDA oversees most other foods from production to retail, enforcing pesticide limits; and the CDC monitors foodborne illness outbreaks. Food product dating labels like sell by, best by, and expiration dates guide freshness and quality but do not guarantee safety. Proper food handling and recognizing spoilage signs are crucial for preventing foodborne illness and reducing waste, with baby formula as a key exception requiring strict adherence to use-by dates.

Food Safety: Regulation & Oversight

Food safety regulation in the United States involves multiple federal agencies, each with distinct but sometimes overlapping responsibilities that span from the farm to the consumer's table. Understanding the roles of these organizations helps clarify how food safety is maintained throughout the food supply chain.

The Environmental Protection Agency (EPA) primarily operates at the farm or food origin level. Its key role is to establish safe pesticide use guidelines and set residue limits, which define the maximum amount of pesticide allowed to remain on food products. These limits are carefully regulated to ensure safety for consumers. Additionally, the EPA sets water quality standards that impact agricultural practices and food safety.

The United States Department of Agriculture (USDA), particularly through its Food Safety and Inspection Service (FSIS), oversees food safety from the farm through processing and production stages. The FSIS specifically regulates and inspects meat, poultry, and eggs, ensuring these products meet safety standards. While the EPA sets pesticide residue limits, the FSIS tests meat, poultry, and eggs to confirm pesticide levels do not exceed those limits.

The Food and Drug Administration (FDA) manages the safety and labeling of most other foods, operating mainly from processing and production up to retail stores. The FDA enforces the EPA’s pesticide residue limits on produce and other non-meat food products. It also regulates nutrition labeling and monitors food safety to protect consumers.

Lastly, the Centers for Disease Control and Prevention (CDC) plays a crucial role in monitoring and investigating foodborne illness outbreaks. Although it does not regulate food safety directly, the CDC tracks illnesses from consumption back to the food origin, helping identify sources of contamination and prevent further outbreaks. The CDC also educates the public about foodborne illnesses and prevention strategies.

Together, these agencies form a comprehensive system that ensures food safety from the farm to the table, combining regulation, inspection, enforcement, monitoring, and education to protect public health.

U.S. Food Safety Systems Example 1

The Environmental Protection Agency (EPA) is responsible for establishing guidelines on the allowed levels of pesticides, ensuring environmental safety and public health. Contrary to some misconceptions, the Centers for Disease Control and Prevention (CDC) does not set these pesticide limits but instead focuses on monitoring outbreaks of foodborne illnesses to protect public health. The Food Safety and Inspection Service (FSIS), a unit within the United States Department of Agriculture (USDA), oversees the inspection of meat, poultry, and eggs, ensuring these food products meet safety standards. Meanwhile, the Food and Drug Administration (FDA) is tasked with overseeing the safety of produce, monitoring pesticide residue levels on fruits and vegetables to ensure they remain below the limits established by the EPA. Understanding the distinct roles of these agencies is crucial for comprehending the regulatory framework that maintains food safety in the United States.

Food Product Dating

Understanding food safety involves recognizing the meaning and regulations surrounding food product dating labels such as the sell by date, best by date, and expiration date. Although these dates are commonly found on food packaging, it is important to note that federal regulations do not require food product dating labels, with the notable exception of baby formula, which must include a use by date to ensure its nutritional quality.

State regulations may impose additional requirements, particularly for fresh foods like eggs, but these vary by state. The primary purpose of these dates is to help consumers gauge freshness rather than guarantee safety. Proper handling and storage of food are far more critical factors in ensuring food safety than the printed dates alone.

The sell by date indicates the last day a product should be sold by the retailer. Consumers can generally purchase and safely consume food for several days after this date, assuming proper storage. For example, fresh milk often carries a sell by date, and it typically remains safe to drink for a few days beyond that date if refrigerated correctly.

The best by or best before date refers to the period when the food maintains its highest quality and flavor. This date is not related to safety; food may still be safe to eat after this date but might experience a decline in taste or texture, such as granola bars becoming stale.

The expiration date or use by date is the most critical for food safety, marking the last recommended day for consumption. While food may not suddenly become unsafe immediately after this date, especially low-risk foods, it is essential to use sensory cues—such as smell, appearance, and texture—to assess spoilage. Signs like off odors, sliminess, or discoloration are reliable indicators that food should be discarded, regardless of the printed date.

Using sensory evaluation alongside date labels helps reduce food waste by preventing premature disposal of still-edible products. For instance, a block of cheddar cheese can remain safe well past its sell by date if stored properly in the refrigerator.

Baby formula is a unique case where strict adherence to the use by date is crucial, not because the formula spoils immediately, but because its nutritional quality may degrade, which is vital for infant health.

In summary, while food product dates provide useful guidance on freshness and quality, they do not replace the importance of proper food handling and sensory assessment. When uncertain about the safety of a food item, it is always safest to discard it to prevent foodborne illness.

Which food or foods are required by the FDA to have a best-by, sell-by, or use-by date?

• A. All meats, dairy, & eggs.
• B. All fresh foods that require refrigeration.
• C. Canned goods.
• D. Baby formula.

Answer: (D)

Which is the best way to ensure food is safe to eat? 

• A. Consume food before the sell-by date.
• B. Consume food before the use-by date.
• C. Consume food before the best-by date.
• D. Ensure food has been handled and stored properly, and check for signs of spoilage.

Answer: (D)

A block of Parmesan cheese (a hard cheese) will often be good for several months past its sell-by date, provided that it is appropriately handled. Which option below do you think best explains why that is?

• A. Hard cheeses have very low water content and high acidity, so are at low risk for microbial growth.
• B. The sell-by date is only used by stores; foods are still generally good for months after their sell-by dates.
• C. Hard cheeses are kept refrigerated, and refrigerated foods tend to be safe long after the sell-by date.
• D. Having a sell-by date indicates it’s at low risk for spoilage; foods that are at risk of spoilage will have a use-by date.

What federal agencies are responsible for regulating food safety in the U.S.?

Food safety in the U.S. is regulated by multiple federal agencies, each with specific roles. The Environmental Protection Agency (EPA) sets safe pesticide residue limits and water quality standards at the farm level. The United States Department of Agriculture (USDA), through its Food Safety and Inspection Service (FSIS), inspects meat, poultry, and eggs from farm to processing. The Food and Drug Administration (FDA) oversees most other foods from production to retail, enforcing pesticide limits set by the EPA. Lastly, the Centers for Disease Control and Prevention (CDC) monitors and investigates foodborne illness outbreaks and educates the public about food safety. Together, these agencies work to ensure the safety of the food supply from farm to table.

How do food product dating labels like sell by, best by, and expiration dates affect food safety?

Food product dating labels such as sell by, best by, and expiration dates primarily indicate freshness and quality, not safety. The sell by date tells stores when to remove products from shelves but food is often safe to consume a few days after. The best by date indicates when food is at its highest quality and flavor, but food can still be safe after this date. The expiration or use by date is the most critical for safety, marking the last recommended day for consumption. However, food may still be safe after this date if it shows no signs of spoilage like bad smell or discoloration. Proper handling and recognizing spoilage signs are essential for food safety, with baby formula as a key exception requiring strict adherence to use-by dates.

What role does the EPA play in food safety regulation?

The Environmental Protection Agency (EPA) plays a crucial role in food safety by establishing safe pesticide use and residue limits on foods at the farm level. These residue limits define how much pesticide can remain on food when purchased, ensuring it is at a very low and safe level for consumption. Additionally, the EPA sets water quality standards that impact food production environments. While the EPA sets these safety standards, enforcement of pesticide limits on produce and other foods is carried out by the Food and Drug Administration (FDA), and for meat, poultry, and eggs, by the USDA's Food Safety and Inspection Service (FSIS).

How does the USDA's Food Safety and Inspection Service (FSIS) contribute to food safety?

The USDA's Food Safety and Inspection Service (FSIS) is responsible for regulating and inspecting meat, poultry, and eggs. It operates from the farm or food origin level through processing and production. FSIS ensures that these animal products meet safety standards, including testing for pesticide residues to confirm they do not exceed limits set by the EPA. This agency plays a vital role in preventing contaminated or unsafe meat, poultry, and egg products from reaching consumers, thereby protecting public health.

What is the CDC's role in food safety, and how does it differ from regulatory agencies?

The Centers for Disease Control and Prevention (CDC) does not regulate food safety directly but plays a critical role in monitoring and investigating foodborne illness outbreaks. The CDC tracks illnesses from consumption back to the food origin to identify sources of contamination and prevent further outbreaks. It also educates the public about foodborne illnesses and safe food handling practices. Unlike regulatory agencies like the EPA, USDA, and FDA, which set and enforce safety standards, the CDC focuses on surveillance, outbreak response, and public health education.
