Importance of food safety.
Increased age of human population
Mass tourism and huge international trade of food.
Changes in food habits of consumers.
Increase in the contaminants giving rise to food
borne illness.
New and improved technologies of processing

Risk Analysis
Hazards : potentially harmful natural or artificial substances
contacting during food production or preparation.
Risk : the chance of being harmed by hazards
High Risk
Microorganism
Chemical naturally present
Chemical produced by cooking
Environmental contaminants
Pesticides
Additives
Low Risk
8 Identified Major Risk Factors
Improper holding Inadequate cleaning &
temperatures disinfecting of equipment
Preparing food ahead of Cross contamination
planned schedule Use of left over
Poor personal hygiene Contaminated raw
Inadequate cooking material

Food Safety Management System
GMP : Good Manufacturing Practice
- Environmental Process Management
HACCP : Hazard Analysis And Critical Control Point
- Process Control
Both of which emphasis on Prevention not Correction
HACCP
HACCP is a system which identifies, evaluates, and
controls hazards which are significant for food
safety.
HACCP = Hazard
Analysis
Critical
Control
Point
Background of HACCP
HACCP was originally developed by
Pillsbury Company working along with
NASA and US Army laboratories at
Natick, to ensure the safety of food for
the astronauts.
It is based on FMEA – Failure, Mode,
and Effect Analysis System which
entailed looking at what could
potentially go wrong at each stage in and
operation along with possible causes and
likely effects before developing effective
control mechanisms
HACCP Preliminary Preparations
1. Assemble HACCP team
2. Describe the product and its distribution
3. Identify intended use and customer of the product
4. Develop a flow diagram
5. Check the flow diagram
HACCP Principles
1. Conduct Hazard Analysis
2. Determine the Critical Control Points
using decision trees
3. Establish Critical Limits
4. Establish a system to monitor control of the CCP.
5. Establish the corrective action to be taken when
monitoring indicates that a particular CCP is not under
control.
6. Establish procedures for verification to confirm that the
HACCP system is working effectively.
7. Establish documentation concerning all procedures and
records appropriate to these principles and their application.
HACCP Terminology
Critical Control Point (CCP):
An operation (practice, process, procedure, or location) at which
a preventive or control measure can be exercised that will
eliminate , prevent or minimize hazards to an acceptable levels.
Decision Tree:
A sequence of questions applied to each process step with a
potential hazard to identify which process steps are critical to
food safety.
Critical Limits:
The value of monitored action which separates the acceptable
from unacceptable.
HACCP Terminology
To monitor:
To conduct a planned sequence of observations or measurements to
assess the control of a CCP.
Corrective action:
A specified prompt action to be taken when the criteria are not
met or when the results of monitoring the CCP indicates a
trend towards loss of control.
Verification:
Review of monitoring records to determine whether the
HACCP system is in place an functioning as planned and to
ensure that monitoring is carried out effectively and efficiently.

HACCP Benefits
Enhanced Food Safety and reduced risk of food borne
diseases;
Providing greater confidence to customers;
Reduction in production costs through reduced
wastage;
Facilities compliance with statutory requirements;
Current and potential hazards can be identified and
removed or diminished.
Golden Rules of Food Safety
Choose processed raw materials.
Cook food thoroughly.
Serve cooked food as soon as possible.
Store cooked food at temperatures beyond danger zero.
Reheat cooked food thoroughly.
Avoid cross-contamination
Be clean, keep clean, and serve clean.
Ensure pest control.
Use potable water for cooking.
