[A SURVEY ON ACCIDENTAL INGESTION OF PACKAGED PROCESSED FOODS, EATING OUT AND OVER-THE-COUNTER SALES BY INDIVIDUALS WITH FOOD ALLERGIES].

OBJECTIVE

To determine the frequency and effects of accidental ingestion of packaged processed foods, eating out, and over-the-counter sales in individuals with food allergies.

METHODS

The participants were guardians of children hospitalized for an oral food challenge test during January and February 2016 at the Department of Pediatrics, Sagamihara National Hospital. We conducted a questionnaire survey on food allergies, accidental ingestion via packaged processed foods, eating out, and over-the-counter sales in the past 1 year, and the degree of understanding of the display of allergen-related information.

RESULTS

A total of 442 participants were given questionnaires, and 226 provided valid responses. Among these respondents, 31% had experienced accidental ingestion (packaged processed food: 24%, food service: 12%), and approximately one quarter of the subjects with allergic symptoms had repeated accidental ingestion. About 70% of the causes were due to overlooking or misunderstanding of allergen information. Of the participants, 85% were aware that processed foods must display allergen information, and 39% were aware that there was no requirement to label food sold in food service and over-the-counter sales.

CONCLUSIONS

Patients with food allergies are familiar with and repeatedly experience accidental ingestion of packaged processed foods, eating out, and over-the-counter sales. In order to prevent accidental ingestion, it is important to thoroughly check allergy labeling and to instruct patients on precautions to take when eating out or over-the-counter sales.
