The U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) share primary responsibility for overseeing the safety of the U.S. food supply. In addition, all states have their own laws, regulations and agencies dedicated to food safety. The federal Centers for Disease Control (CDC) is mainly responsible for investigating localized and nationwide outbreaks of foodborne illnesses.
In many cases, the food safety functions of the FDA and USDA overlap; particularly inspection/enforcement, training, research, and rulemaking, for both domestic and imported food. Both USDA and FDA currently conduct similar inspections at some 1,500 dual jurisdiction establishments -- facilities that produce foods regulated by both agencies.
Role of the USDA
The USDA has primary responsibility for the safety of meat, poultry and certain egg products. USDA's regulatory authority comes from the Federal Meat Inspection Act, the Poultry Products Inspection Act, the Egg Products Inspection Act and the Humane Methods of Livestock Slaughter Act.
USDA inspects all meat, poultry and egg products sold in interstate commerce, and re-inspects imported meat, poultry and egg products to makes sure they meet U.S. safety standards. In egg processing plants, the USDA inspects eggs before and after they are broken for further processing.
Role of the FDA
The FDA, as authorized by the federal Food, Drug and Cosmetic Act, and the Public Health Service Act, regulates foods other than the meat and poultry products regulated by the USDA. FDA is also responsible for the safety of drugs, medical devices, biologics, animal feed and drugs, cosmetics, and radiation emitting devices.
New regulations giving the FDA the authority to inspect large commercial egg farms took effect on July 9, 2010. Prior to this rule, FDA inspected egg farms under its broad authorities applicable to all food, focusing on farms already linked to recalls. Apparently, the new rule did not take effect soon enough to allow for proactive inspections by the FDA of the egg farms involved in the August 2010 recall of nearly half a billion eggs for salmonella contamination.
Role of the CDC
The Centers for Disease Control leads federal efforts to gather data on foodborne illnesses, investigate foodborne illnesses and outbreaks, and monitor the effectiveness of prevention and control efforts in reducing foodborne illnesses. CDC also plays a key role in building state and local health department epidemiology, laboratory, and environmental health capacity to support foodborne disease surveillance and outbreak response.
All of the federal laws listed above empower the USDA and FDA with different regulatory and enforcement authorities. For example, food products under FDA's jurisdiction may be sold to the public without the agency's prior approval. On the other hand, food products under USDA's jurisdiction must generally be inspected and approved as meeting federal standards before being marketed.
Under current law, UDSA continuously inspects slaughter facilities and examines each slaughtered meat and poultry carcass. They also visit each processing facility at least once during each operating day. For foods under FDA's jurisdiction, however, federal law does not mandate the frequency of inspections.
Following the terrorist attacks of September 11, 2001, the federal food safety agencies began taking on the added responsibility of addressing the potential for deliberate contamination of agriculture and food products - bioterrorism.
An executive order issued by President George W. Bush in 2001 added the food industry to the list of critical sectors that need protection from possible terrorist attack. As a result of this order, the Homeland Security Act of 2002 established the Department of Homeland Security, which now provides overall coordination for protecting the U.S. food supply from deliberate contamination.
Finally, the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 granted the FDA additional food safety enforcement authorities similar to those of the USDA.
