Outbreaks of Disease Associated with Food Imported into the United States, 1996-20141.

The proportion of US food that is imported is increasing; most seafood and half of fruits are imported. We identified a small but increasing number of foodborne disease outbreaks associated with imported foods, most commonly fish and produce. New outbreak investigation tools and federal regulatory authority are key to maintaining food safety.

Prevalence of self-reported food allergy in American adults and use of food labels.

BACKGROUND: Few population-based studies in the United States have determined the prevalence of food allergy in adults and the problems these individuals might have with reading food labels. OBJECTIVE: The objectives of this study are to report the prevalence of self-reported food allergy, to identify the characteristics of food allergy reactions, and to describe the use of labels among adults with food allergy. METHODS: Questions from the US Food and Drug Administration's 2001 Food Safety Survey were analyzed to determine the prevalence of food allergy and opinions about food labels in the management of food allergy. RESULTS: The prevalence of self-reported food allergy is 9.1% among all survey respondents, with 5.3% of all respondents reporting a doctor-diagnosed food allergy. The prevalence of food allergy to the 8 most common allergens (peanut, tree nuts, egg, milk, wheat, soybeans, fish, and crustacean shellfish) is self-reported as 2.7% among respondents with doctors' diagnoses. Several label issues, such as words on some ingredient lists being too technical or hard to understand and food labels not always alerting persons to new ingredients, were reported as serious or very serious obstacles for managing an allergy. CONCLUSION: The prevalence of self-reported doctor-diagnosed food allergy among US adults is 5.3%, and a large portion of adults with food allergy found certain label issues a serious problem for managing their food allergy. CLINICAL IMPLICATIONS: The findings provide a needed source of population-based prevalence data of food allergy among US adults. Label issues identified are useful in understanding the difficulties of managing a food allergy.

Recalls of foods containing undeclared allergens reported to the US Food and Drug Administration, fiscal year 1999.

BACKGROUND: Food recalls can play a role in preventing or reducing the number of allergic reactions that may occur after a product containing an undeclared allergen has been introduced into commerce. OBJECTIVE: We sought to summarize the US Food and Drug Administration's records of recalls classified for fiscal year 1999 involving foods containing undeclared allergens. METHODS: Food and Drug Administration food recall records were reviewed for fiscal year 1999 to identify recalls that occurred because of the undeclared presence of one or more of the following allergens: milk, eggs, fish, wheat, crustacean shellfish, tree nuts, peanuts, and soy. Each record was reviewed to determine the recalled product, the undeclared allergen present, the reason for recall, and reported adverse events. RESULTS: Of 659 total food products classified for recall during fiscal year 1999, 236 (36%) products were recalled because they contained one or more undeclared allergens. Consumers were the party most often responsible for identifying that an undeclared allergen was present in a product (56% of recalled products). A total of 34 consumers reported allergic reactions after consumption of the recalled products. Three principal factors contributed to the presence of undeclared allergens in the recalled products: ingredient-statement omissions and errors (51% of all recalled products); manufacturing equipment cross-contact (40%); and errors by ingredient suppliers or manufacturing firm employees (5%). CONCLUSION: The presence of undeclared allergens in food products represents one of the more common reasons for food-product recall in the United States. A number of well-recognized allergens may be introduced into foods as a result of several different factors.
