HACCP–HazardAnalysisandCriticalControlPoints Foodsafety isamajorfactorandquality insurance issue.TheHACCPsystemisusedtoensurefood for consumers and foodworkers are safe. It is a qualitymanagement technique (compulsory insomesectors)thatidentifiespotentialhazardswithintheproductionoffoodproductsandmethodsofdealingwiththem.Thereare7stepsintheHACCPregimethatareinternationallyknown:
1. Assesshazards–ahazard isanysituation inwhicha food iscontaminatedandmayharmtheconsumer.Freshpoultrycontainssalmonellabacteriasocan’tstorewithvegetables
