RSSL crack the crustacea allergen challenge

RSSL has developed a test to identify trace amounts of crustacea, adding to the comprehensive list of allergen tests that the specialist laboratory can perform to UKAS approved standards. Using the DNA amplification technique of PCR, RSSL can detect the presence of different crustacea species, such as shrimps, prawns, crabs, lobster and crayfish in a wide range of food products. The test is sensitive down to 100ppm.

Crustacea are on the EU list of 12 allergens that have to be labelled if present in a food. Clearly, there are situations where it will be obvious that crustacea will have been used in food products. However, as with all allergens, the serious risk to consumers comes from the potential for cross contamination and inadvertent inclusion in factories where several products are processed on the same line, or where ingredients are stored in close proximity. In addition to providing testing services for crustacea and other allergens, RSSL can also advise on 'free-from' production and offers consultancy and training in related disciplines such as HACCP.
