Doug,
You are probably aware that the
HACCP Plan is a dynamic set of documents that should be reviewed regularly to ensure that it is functioning as intended.
However, in this case, if I may safely assume that the difference in ingredients load do not affect the
critical control points of the process structure specifics. If thats the case, the exposure to food process risk has not heightened and as such, the new product formulation shall be recorded in replacement of the old.
However, if the change in product formulation is significant in terms of change of suppliers, materials, process control points such as temperature/time etc, then a risk assessment should be performed to ascertained whether risks have heightened or new risks have surfaced due to the change.
What I do is, the form format is basically the same as a
CCP determination / hazard analysis worksheet.
