Regulations require slaughterhouses to implement measures to prevent any CNST (especially those considered SRM) from cross-contaminating other tissues at slaughter.
Therefore, in order to make the prevention of CNST contamination more practical, a method should be developed to avoid the CNST dissemination during splitting.
The first group was conducted to examine the effect of different washing times and methods after spinal cord removal on CNST decontamination.
The second group was conducted to compare the effect of spinal cord removal before or after splitting on interior carcasses for CNST decontamination.
Detection of CNST was performed on samples using a commercial ELISA-based test - the Ridascreen[TM] risk material 10/5 kit (R-biopharm, AG, Darmstadt, Germany), which detects glial fibrillary acidic protein as a marker.
Effects of different washing time and methods after spinal cord removal on CNST decontamination
Based on the assay instructions, positive CNST contamination existed at more than 0.
The effects of washing methods after spinal cord removal using vacuum suction for CNST decontamination is shown in Figure 3.
Effects of spinal cord removal before and after splitting on CNST decontamination
The effect of spinal cord removal before and after splitting on carcasses for CNST decontamination is shown in Figure 4 and 5.
CNST assesses maternity services in the UK against eight clinical risk standards, which, if in place, demonstrate that high quality and safe care for mothers and babies is being provided.
To achieve CNST Level 2, very high standards must be attained in areas including general organisation in the unit, training of staff, record keeping and clinical care.
