Safer, More Reliable Method to Test for Trichinella in Pork

EU - Germany-based Gütersloh Veterinary Services recently shared its experience in routine Trichinella testing in swine carcasses with the validation and implementation of the PrioCHECK™ Trichinella AAD from Thermo Fisher Scientific, a new alternative artificial digestion method which offers many benefits, including worker safety and constant product quality.

In the meat inspection process, pepsin digestion tests have traditionally been used to test for Trichinella in swine carcasses.

However, poor availability and quality of pepsin along with rising pepsin prices have caused Gütersloh to test this innovative artificial digestion method.

The PrioCHECK Trichinella AAD method uses digestion with the enzyme subtilisin, which is recombinantly produced in a standardised and certified production facility. Gütersloh officials said this helps ensure good availability of the enzyme and consistent quality.

Gütersloh officials also said the method helps ensure worker safety because there is no handling of strong acids. Components are all available as liquids, so no weighing of powder is required which further eases implementation. Also, there is no need to decontaminate liquids and devices, as the larvae are killed during digestion. The method detected all test samples in the validation correctly.
