Accreditation (see Certification)
A procedure by which a recognised independent body accredits organisations which are involved in the certification of quality systems, products, services or personnel, to recognised national and/or international standards. The accreditation body may also carry out accreditation inspections in its own right. In Ireland the official national organisation for accreditation is the National Accreditation Board (NAB) e.g. NAB has accredited the National Standards Authority of Ireland (NSAI) for the certification of quality inspections and in its own right NAB has accredited many food testing laboratories in Ireland for analysis of food.

High-Risk Foods, Ready-to-Eat Food) The date up until a food can reasonably be expected to be safe toconsume if kept under the correct storage conditions. ‘Use-by’ datesare more about safety than quality, e.g. high-risk foods such asprepared salads, meat and dairy products have ‘use-by’ dates.
Validation (see Control, Records, Monitoring, Specification, Traceability etc)
Obtaining evidence that the elements of a HACCP plan are effective e.g. microbiological examination of equipment surfaces before and after sanitation to determine if the sanitation procedure was effective in reducing numbers of microorganisms to desired levels.
Vegetative Microorganism (see Spore Forming Microorganism)
A form in which a microorganism is able to grow, given the correct conditions. Unlike spores, vegetative cells are relatively poor at surviving environmental stresses such as high temperature e.g. Salmonella bacteria are vegetative cells and do not produce spores.
