Components of HACCP
HACCP teams and management
The seven principles
Applications
4. HACCP A preventative approach to enable the production of consistently safe products:
Control of key steps (critical control points) which can eliminate or reduce the likelihood of a hazard occurring
Documentation that the system is working
Use of HACCP:
Together with the prerequisite plan, it is the basis for successful implementation of a quality assurance system in the processing of food
Main objective is to ensure products are safe to consume
The concept can also be used in other systems such as drinking water treatment and distribution and agriculture
Monitoring and verification:
HACCP program compliance requires that establishments have systems in place to monitor and control the program and maintain records demonstrating due diligence
5. HACCP Definitions Hazard – any biological, chemical or physical property that may be expected to cause an unacceptable health risk to consumers if present in the product
Risk – an estimate of the likelihood of the occurrence of a hazard
Severity of risk – the seriousness of a hazard if not properly controlled (e.g., metal fragments vs. botulinum toxin)
Critical control point (CCP) – a specific point in a process where control can be applied to eliminate or reduce the risk of a hazard to an acceptable level
6. History of HACCP First used in the US space program to ensure food safety for astronauts without relying on end-product testing (early 1970’s) HACCP was adopted in 1973 by the USFDA for low acid canned food regulations (pH > 4.6) The USFDA made HACCP mandatory for all seafood processors in the US as well as for those foreign plants exporting to the US (1997) Canadian Food Inspection Agency (CFIA) made HACCP mandatory for all Canadian seafood processors (1998) CFIA also implemented mandatory HACCP for the meat and poultry industry (2007) Similar legislation has been imposed in the EU for food processors within the EU and those exporting to EU countries (Internationally Codex Alimentarius)
