Peanut allergy is one of the most common food allergiesStudies showed that peanut allergy in children increased from 0.5 to 1.5% between 1989 and 1994-6 in the UK and 0.6 % to 1.2 % between 1997 and 2002 in the USA. At the same time, in Australia, admissions to hospital for food allergies increased significantly. As Australians became more concerned about food allergies, intolerances, and the effects of chemicals and food additives, demand for more information on packaging increased.
