Pre-requisites: a help or a hindrance to HACCP?

Formal pre-requisite programmes are increasingly and successfully used to support the implementation of HACCP in food processing. However, in many areas there is a lack of understanding of the pre-requisites concept, and even a fear in some sectors that pre-requisites might dilute the strength of HACCP, making it a less effective food safety control mechanism. This paper explores the concept of pre-requisite programmes and discusses whether they are of benefit to the HACCP approach or whether food safety is best managed through the HACCP plan alone, concluding that they are an essential element in the task of developing simple, effective HACCP systems
