5.2. Enhancing HACCP decisions in control points by using QMRA
In each control point the results of the QMRA analysis can be used in order to confirm that the safety of the product has not been compromised. The QMRA will provide an estimate of the probability that the consumer becomes ill due to consumption of the product. This estimate will be based on the information from tests for selected SFP, which will be performed in required points in the SC, and the data supplied on environmental parameters (T, pH, NaCl%). If data from tests is not available then historic data can be used, but only after the system has been operational in the SC sufficiently long period of time to generate reliable historic data. The historic data will not give the actual state, but it will give the probability for certain state based on past data, e.g., PDFs for prevalence and bacterial count. The HACCP should be designed in such way that the procedures are specified for the case when the QMRA information is available in certain part of the chain or when it is not available due to problems in communication with the DSS. If the information from the DSS was not available at certain point the decision of the HACCP has to be checked for that point as soon as the QMRA information becomes available.
