                                Since January 2012, UK food manufacturers and caterers have been required by law to adhere to a specific gluten-free threshold. This standard dictates that a product can only be labelled 'gluten-free' if it contains 20 parts per million (ppm) of gluten or less, a limit set to protect the health of individuals with coeliac disease.
