Over the last six years, allergy deaths have increased by 42% in Australia, and this might explain why the country has among the highest allergy rates in the world. It is partly attributed to the lack of enough nutritional information on food product packaging. It happens although food processors must inform consumers about the contents of their products. To provide accurate nutritional information, food processors must conduct allergen testing. While there are numerous immunological methods of allergen testing, polymerase chain reaction (PCR) testing has proved to be the most reliable.
