Give 6 factors of a goiod PM inspection
- Take into account ante-mortem inspection results;
- View all external surfaces;
- Pay particular attention to the detection of zoonotic and notifiable diseases;
- Take into account FCI;
- Take place without delay after slaughter;
- Include carcases and accompanying offal.
What are the three potential outcomes of a PM inspection?
– pass the meat as fit for human consumption;
– declare the meat unfit for human consumption;
– detain the meat for further examination following rectification.
