Chapter 6
Food Safety Management System
Elements to ensure food safety
Management system
Prerequisite programs
Interactive communication
HACCP principles
Hazard Analysis Critical Control Point (HACCP)
7 principles:
Implementing continuous monitoring
Implementing corrective measures
Establishing critical limits
Verification, validation
Identifying Critical Control Points (CCPs)
Documenting, record-keeping
Identifying hazards, accessing less risks
Purpose:
A systematic preventive approach to food safety from biological, chemical, and physical hazard in production processes that cause an unsafe food
Importances:
A cost effective for foodborne hazards
Leads to reduced product losses
Increase customers satisfaction and confidence
Focuses on prevention and control of hazards
Strengthened public health protection
Provides the framework to produce food safety
Food Microbial Quality and Safety
Food Quality Indicator
To predict product shelf-life
Criteria
should be easily detected, enumerated, and clearly distinguishable
should be enumerable in short time
their growth and numbers should have a direct negative correlation with product quality
their growth should not be affected by other components of food microbiota
should be present and detectable
Indicators
Ethanol
Trimethylamine
Diacetyl
Food Safety Indicator
Criteria
easily distinguishable
organism which numbers ideally should correlate with the pathogen
always be present when pathogen is present
have a die-off rate, ideally persists longer than the pathogen
easily and rapidly detectable
absent from foods that are free from pathogen
have a history of constant association with the pathogen
possess growth requirements and growth rate >= to the pathogen
Indicators:
Enterococci
Bifidobacteria
Coliforms
Coliphages/Enteroviruses
To assess food safety and sanitation
Limitations:
poultry products
meats
frozen blanched vegetables
Laboratory testing and reporting
most probable number (MPN)
direct plating
filter-based method
