SUMMARY

The mission of the Center for Food Safety and Applied Nutrition (CFSAN) of the Food and Drug Administration focuses on promoting and protecting the public’s health by ensuring that the nation’s food supply is safe, wholesome, sanitary, and honestly labeled.  CFSAN monitors the food industry’s response to food labeling regulations through the Food Label and Package Survey (FLAPS). FLAPS data characterize the presence of food safety and other information for the consumer.  The labels of close to one-third of the food products sold in the United States include statements about refrigeration, but the words “to maintain safety” are not present, even though FDA guidance indicates the importance of including them.  Consumers are concerned that labels contain information to alert allergic individuals to the presence of food allergens, but very few food labels voluntarily bear such information. Regulations do not require food manufacturers to provide information on bioengineered ingredients, and very few manufacturers voluntarily do so.  Pasteurization is used to kill pathogens that could cause illness or death, and regulations require a warning statement on the label of juice products that have not been pasteurized or otherwise processed to prevent, reduce or eliminate pathogenic microorganisms.  Over half of juices have a statement that they are pasteurized.  Few foods contain information to cook foods thoroughly or to use a thermometer.  The food label can be used as an educational tool and will be one of the primary vehicles to provide critical information to the consumer.

 


Acids, Pathogens, Foods and Us

SUMMARY

Acids have a lethal or inhibitory effect on microorganisms when they are in high enough concentrations to denature proteins, when they are transported into cells, or when they cause protons to leak into cells increasing the amount of energy needed to maintain the internal pH.  Acids have been used to preserve foods for centuries. In recent years they have been applied to surfaces of fresh meats, ready-to-eat foods, vegetables and fruits to destroy pathogens. The major acids used have been acetic, propionic, and lactic. Combinations of acids and other chemicals can be highly toxic to bacteria. Examples include acidified calcium sulfate and acidified sodium chlorite. Bacterial tolerance to acids often increases on exposure of them to moderate concentrations of acids.
