Key points
The Food and Drug Administration (FDA) was initiated in 1906 when Congress passed the Food and Drug Act and charged the agency with prohibiting the interstate transport of adulterated or mislabeled foods or drugs.
Department of Agriculture (USDA) is responsible for overseeing the approximately 20% of our food supply provided by meat, poultry, and eggs.
As the major agency responsible for monitoring health and disease, the Centers for Disease Control and Prevention (CDC) develops disease prevention strategies that are based on sound scientific evidence, monitors ongoing health problems, develops public health policies, and promotes healthy behaviors.
The Environmental Protection Agency (EPA) is responsible for protecting the American public from any health risks caused by eating foods contaminated with pesticides.
The Food and Drug Administration (FDA) was initiated in 1906 when Congress passed the Food and Drug Act and charged the agency with prohibiting the interstate transport of adulterated or mislabeled foods or drugs. Chemists and inspectors were hired, and they set about the task of protecting the public from the unhealthy practices of the food industry. However, they soon ran up against a problem that continues to this day: The food and beverage industries are huge and politically powerful, and they fought back against regulation by this upstart agency. A controversial addition to the FDA's authority was nicknamed the "Delaney clause." The law established a "zero tolerance" policy for any additive or pesticide residue in processed food that was found to cause cancer.
Consumer groups opposed the Delaney clause, claiming it did not protect the public because of the many loopholes that the clause contained. The agriculture industry opposed it because it barred the use of possibly safe pesticides. The fight raged on for years in Congress and in the courts. Finally, Congress passed reform legislation for food safety in 1996. The Delaney clause was gone but in its place came powerful new protections for consumers.
Today's FDA is one of the United States's largest government agencies. It is responsible for promoting health by reviewing research and approving new products, ensuring that our foods are safe and properly labeled, and working with consumer groups and scientific experts. As part of the Department of Health and Human Services, the agency works closely with Congress, many other federal agencies, and state and local health agencies to assure the safety of our food supply. Despite its size, the FDA has not been able to keep pace with the growth and complexity of the food production industry. Many domestic food processing plants are not visited by an inspector more than once every five years.
The FDA is also charged with inspection of the imported food supply, which has grown rapidly in recent decades. Many of these imported foods come from countries with inadequate controls over production methods, yet it is impossible for the FDA to inspect all foods entering the United States. In 2006, FDA inspectors sampled less than 3% of the food shipments that arrived at American ports.
In addition to the FDA's primary goal of preventing any contamination of our food supply, the FDA is also active in responding to evidence of any failure of the safety network.
It works closely with the Centers for Disease Control and Prevention (CDC) in cases of suspected disease outbreaks related to food sources. Computer networks among the 50 states are available to react quickly in the event of food-related illnesses. Efforts are underway to expand the FDA's reach in light of the increasing seriousness of growing food scares and to deal with the ever more complex food supply system.

The U.S. Department of Agriculture (USDA) is responsible for overseeing the approximately 20% of our food supply provided by meat, poultry, and eggs. They work to assure that these products are safe, wholesome, and correctly packaged. America is a nation of meat eaters; the average person eats more than 200 pounds (91 kilograms) of meat each year. Unfortunately, meat and poultry products are at high risk of contamination by bacteria that can cause illness.
Meat processing is a tough and dirty business, just as it was in the days when Upton Sinclair exposed its practices in e Jungle. The USDA oversees inspection of meatpacking and poultry processing plants, and the testing for contaminants that could cause illness. In cooperation with other agencies, they respond to evidence of illnesses caused by consumption of meat products. Consumer education about nutrition and food safety is a major part of their mission.
Much of the foodborne illness caused by meat, poultry, and egg products can be eliminated through careful cleaning during food preparation and thorough cooking.

Centers for Disease Control and Prevention
As the major agency responsible for monitoring health and disease, the Centers for Disease Control and Prevention (CDC) develops disease prevention strategies that are based on sound scientific evidence, monitors ongoing health problems, develops public health policies, and promotes healthy behaviors. It provides expertise to local health agencies and has emergency teams ready to go into the field in cases of major outbreaks of foodborne illness. Through its Office of Food Safety, it keeps track of individual cases of foodborne illness and partners with other agencies to investigate outbreaks. The CDC estimates that as many as 76 million people in the United States experience a foodborne illness each year, and approximately 5,000 die from it. The CDC operates the FoodNet survey system to monitor the impact of foodborne illnesses on public health. These illnesses are difficult to track accurately because many cases are never reported. Also, it may not be clear in particular cases if an illness was due to a food or water source, or if it was spread by some other means.
Environmental Protection Agency
The Environmental Protection Agency (EPA) is responsible for protecting the American public from any health risks caused by eating foods contaminated with pesticides. Before any new pesticide can be applied to a food crop, it must be thoroughly tested for safety and approved by the EPA. The pesticide can only be used on the specified crop and must be applied in the manner approved by the EPA.
Pesticides play a major role in modern agriculture, protecting crops from the effects of weeds, insects, fungi, and rodents.
COUNTING THE CASES Most cases of foodborne illness are so mild that the individual does not consult a physician. No testing is done to determine what organism caused the illness, and no public health system is notified. Yet the CDC estimates that 76 million people are affected each year in the United States. How do scientists have any idea of the numbers of cases of infection, and how many are due to various types of pathogens?
Since 1996, the CDC has operated FoodNet, the Foodborne Diseases Active Surveillance Network. It represents a cooperative effort among the CDC, USDA, FDA, and 10 state health departments. Its purpose is to provide accurate and ongoing estimates of the extent of foodborne diseases in the United States, to provide a breakdown of infections by type of pathogen, and to monitor trends in illness over time.
The geographic areas in the survey include more than 15% of the population.
Data are collected on all laboratory-confirmed positive specimens for nine food-related pathogens, along with information on the person's age, gender, and whether the illness resulted in hospitalization. This information is supplemented by surveys of physicians, laboratories, and the general population within the study areas. Using these additional data, researchers are able to estimate, for each positive specimen, how many other people see their physicians without undergoing specimen testing, and how many people in the general population are sick with a suspected foodborne illness but do not visit their physician. Statistical methods incorporating these data allow researchers to estimate the extent and types of foodborne illnesses in the entire U.S. population.
The information allows the CDC to take actions aimed at disease prevention where they will have the largest impact. Also, the information allows them to track the impact of their interventions based on whether numbers of cases of illness go up or down following the intervention.
In recent years, the numbers have remained fairly constant, suggesting that further interventions are needed in order to reduce the impact of foodborne illnesses.

Even when pesticides are applied as approved by the EPA, small amounts of the chemicals may remain on fruits, vegetables, or grains. As a result, traces of pesticides may be on the fresh produce that reaches the consumer, or in processed foods sold at the grocery store. The EPA sets maximum allowable levels of pesticides that may remain on or in foods. These levels are set many times lower than what tests indicate could actually harm human health. The FDA and USDA are responsible for monitoring pesticides in foods to be sure the allowable levels are not exceeded.
The EPA is responsible for setting safety standards for public water supplies. They determine what levels of chemicals may safely be present in drinking water without causing risk to human health.
An EPA hotline provides information to consumers about drinking water quality.
