Your CCP should be validated PRIOR to implementation. You hazard analysis has determined you need them..........now you have to VALIDATE the limits
Sometimes that is really straight forward, say metal detection.....some countries have legislated maximum limits for the different materials..........you then just have to run a series of tests in situ to make sure your process can capture those limits and then set frequency for monitoring
However, if you determine you have a CCP for something like e coli.........you would have to back up your CCP with scientific papers that show under conditions X the e coli is removed/reduced to an acceptable limits (think carcass/veggie washing here)
Remember, nothing in a HACCP plan is written in stone.........so you try to validate a CCP as you think it should work, and your validation study doesn't hold up.....then change the parameters of the CCP
Scheintzelman ...........if you share the product type we can assist a lot more............I also suggest you have a look at this link

IMHO the FSEP manual is one of the very best HACCP models going and is full of very useful information (plus CFIA inspectors are used to it so moving forward into SFCR it will be easier for you and them)
Feel free to ask me directly----have been working in a CFIA inspected facility for 10+ years and there are not a lot of Canadians on this site
