In 2008, we undertook a survey of food products that carried precautionary labeling within the Australian supermarket setting. We then repeated the same survey in 2011 to examine changes in the prevalence of precautionary labeling over a 3-year period. Our results showed that overall 65% of products contained 1 or more precautionary statements to any of the nine most common food allergens (peanuts, tree nuts, egg, milk, sesame, crustaceans, fish, wheat, and soy). We also have recently examined consumers’ behavior, perceptions, and opinions about precautionary labeling, which showed that even those with a history of anaphylaxis to food appeared to be complacent for avoidance of foods with precautionary labeling, perhaps because of their ubiquity or because the perceived risks are low.
