Reading Scientific Services Ltd has gained UKAS accreditation for its BSE testing service - the first and only commercial testing service for BSE in the UK. The accreditation comes just a couple of months after RSSL first launched the service. The equipment and testing methodology used by RSSL was developed by Bio-Rad. It is considered to be the most sensitive and reliable test for detecting the BSE prion in brain stem material taken from the animal carcass. It is the prion protein that is thought to cause BSE in cattle, and is considered by some to be the causative agent of new variant CJD in humans.
