Food Safety

Foodborne diseases are largely preventable—but the goal requires vigilance in every step from the farm to the table. Good agricultural and manufacturing practices can reduce the spread of microbes among animals and prevent contamination of foods.
Advocates have recommended that all food safety activities be consolidated into a single federal agency with a unified mission.
Monitoring the entire food production process can pinpoint hazards and identify control points where contamination can be prevented, limited, or eliminated. A formal method for evaluating risk control is called the Hazard Analysis Critical Control Point, or HACCP (pronounced “has-sip”), system. First developed by the National and Aeronautics Space Administration to ensure that the food eaten by astronauts was safe, HACCP safety principles are now being applied to a widening range of foods, including meat, poultry, seafood, fruit juices, and other products.
 
In recent years, the U.S. Government Accountability Office, food safety advocates, and legislators have documented problems resulting from the fragmented nature of the nation’s food safety system. At least a dozen federal agencies, implementing at least 30 different laws, have roles in overseeing the safety of the nation’s food supply. Advocates have recommended that all food safety activities be consolidated into a single federal agency with a unified mission.

What do you know about infectious disease?

If you have strep throat, which of the following forms of medication can be used to effectively treat the infection?

  • Sorry, that’s incorrect.

    Because strep throat is caused by a bacterium called Streptococcus pyogenes, it is treatable with antibiotics but not antivirals. Currently there is no vaccine available to prevent strep throat.
