Microbiological food safety is achieved by strict adherence to Good Manufacturing Practices and implementation of adequate control measures in the production process to prevent the entry, survival, and/or growth of pathogens. The application of rapid methods can be a great advantage to respond quickly to outbreaks, reject contaminated raw materials before they enter the production chain, rapidly identify process failures to take corrective measures. This chapter provides an overview of criteria that can be useful to judge the suitability of a method. The criteria includes reliability, validation, acceptance by public health authorities and trade partners, time to result, costs, laboratory space, sample throughput, shelf life of reagents, competency level and workflow compatibility, and supply chain confidence. The chapter provides some general examples of the relative importance of these criteria for different applications, but it is up to the user to define which criteria are really essential and which are only desirable. Once the selection criteria are established, the next challenge is to find reliable information on how candidate methods score with respect to the requirements.
