Risk-based inspection optimization

The management of pressure systems equipment integrity can be risk-based or time-based however, risk-based is preferable in order to prioritize and optimize the resources. The risk-based inspection schemes can be either quantitative, semiquantitative, or qualitative, depending on the inspection and corrosion historical data available for risk assessment that will be used where necessary to derive inspection schemes and provide the foundation for planned integrity activities. 

If both the farms and the dairy are covered by a reliable control system, the everyday monitoring will take place at the optimal CCP at the farm and analysis of milk samples at the dairy will only be needed at low frequency for verification of the system (Principle 6). This will ensure that there are no antibiotic residues in the milk sold by the dairy, with minimal expenses for control. In fact, the most expensive item will be the cost of the unannounced inspections at the farms to monitor the integrity of the system. However, if not all the farms are covered by a sufficiently good control system, the dairy will have to add the extra costs of its own independent system, in order to be able to take responsibility for this quality aspect. So the main benefit of a supply chain-based system is that it provides full control at the lowest cost. The main drawback is that the more entities that are involved, the greater is the risk that one of them will experience a system failure and this can have disastrous consequences for all those other entities that rely on the defaulting entity for their product control.
