How the probability of a hazard is concluded
For example, in receiving the raw materials, the probability of certain hazard occurrence we will consider :
the occurrence probability in the raw material itself
or
the occurrence probability in the next step
or
the occurrence probability in the finished product.
Please reply, even if there is a reference, I am very grateful
Hi Mohamed,
Hazards at the receiving raw materials stage are usually handled as PRPs so no need for a specific risk assessment.
Assuming you refer to Codex/iso haccp, the risk associated with a hazard at any particular stage can be expressed as risk = likelihood of occurrence in the finished product at consumption x severity if occurring.
quoting iso22000:2018 -
The organization shall evaluate each food safety hazard with regard to:
a) the likelihood of its occurrence in the end product prior to application of control measures;b) the severity of its adverse health effects in relation to the intended use
etc
