HACCP is a recognized worldwide as the most effective managing system in which food safety is addressed through the analysis
and control of biological (microbes & toxins), chemical, and physical hazards in food manufacturing, storage, distribution, and con-
sumers consumption. Although biological contamination of food can lead to health hazard to consumers or even death in addition to
the case of food biological contamination.
Implementation of HACCP system in a food organization means control over stages of food manufacturing from raw materials,
processing, storage, distribution, to consumers handling in order to ensure food safety for consumption.
This proactive system of HACCP as a mean of controlling all aspects of food safety, has made this system desirable to food manu-
facturing, retails, food service and to worldwide food regulation agencies. HACCP systems are currently implemented internationally
in all food operations to build food safety for agricultural production, food manufacturing, retail, and food service.
Introduction
HACCP was developed in the early 1960 when the National Aerospace Agency (NASA) asked Pillsbury a United States food company to
produce food that could be used under zero gravity [1]. The problem of unknown behavior of food product under zero gravity was solved
quickly, but Pillsbury company recognized that the existing destructive quality control techniques for food safety are not reliable for such
special food products to assure complete eliminating potential contamination in such special foods from biological, chemical or physical
Natick Research Laboratories, and National Aerospace Agency (NASA) resulted in developing a non-destructive quality assurance system
for food safety relied on preventive action by control and record keeping over complete food process steps from raw materials to the end
product distribution [2]. This developed non-destructive quality assurance system for space program food safety project was the initia-
tion for the current HACCP plan system.
The initial developed HACCP system was presented in the year 1971 by Pillsbury food company at the Conference on Food Protection
(CFP) sponsored by Food and Drug Administration (FDA). This presented HACCP system consists of three HACCP plan principles [3].
These three HACCP principles are:
• Establishment of a system or systems to monitor the critical control points.

The outcome from this 1971 conference is a training program managed by Pillsbury Food company scientist to FDA inspectors for the
inspection of canned foods. The title for this training program was “Food Safety through the Hazard Analysis and Critical Control Point

year 1993, The National Advisory Committee of Microbiological Criteria for Foods (NACMCF) revised HACCP guidance standard, adding
the hazard analysis process. Currently, HACCP is an internationally recognized system for reducing the risk of safety hazards in foods for
both domestic and international food production [6].

Principle (2): Identifying critical control points (CCPs)
Identify a control procedure that can be applied in each food process step to eliminate food safety hazard or reduce the hazard to
acceptable limit in the end product. Identify CCPs that might be required in food process steps are by using a CCP decision tree method
(Figure 2). In some cases, one CCP may control more than one step in food process, or control more than one food safety hazard. In other
cases, more than one CCP is needed to control a single hazard in a single food process step. Having said that, the number of CCPs for food
process depend on the nature of food and the type of the control needed to assure the food safety of the end product.
Figure 2: Example of CCPs decision tree for one food process step. The diagram shows hazard concern questions for
one step in the process with answers yes or no that assist in making a CCP decision.
Principle (3): Establishing critical limits (CL)
Critical Limit (CL) is the limit to which biological, chemical, or physical hazard that must be controlled to prevent, eliminate or reduce
-
perature, moisture, pH, water activity (Aw) or any other methods that are acceptable by regulatory standards.
Principle (4): Implementing continuous monitoring
Monitoring food process steps by the measurement of the critical limit (CL) at each designated critical control point (CCP) must be
described including how, when, frequently the measurement taken and who is responsible for taking these measurements during produc-
tion process.
Principle (5): Implementing corrective measures
Corrective actions are the procedure that must be taken when monitoring indicate that there is a divination from the established
critical limit (CL) in a critical control point (CCP). Taking appropriate corrective action in the event of a divination at CCP is essential for

by third party or by regulatory agencies.
Principle (7): Documentations and records keeping

Finally, it important to highlight that the application of HACCP plan in food manufacturing is not suffusion for food safety if stand-
alone in food operation [5]. The HACCP plan must be built with other food safety programs of Good Manufacturing Practice (GMP), and
Sanitation Standard Operation Procedures (SSOPs).
Good manufacturing practice (GMP)
GMP is a set of operational requirements address both food safety and quality issues that are not critical for the reduction of food
safety hazards [7]. Also, it is guidelines that are essential foundation for the development of successful HACCP plans. These guidelines
provide guidance for food manufacturing, sanitation protocols, testing methods, and quality assurance in order to assist in reducing the
risk of foodborne illness and to secure the production and distribution of safe foods with acceptable quality for human consumption.
In summary, GMP practices follow the following standard principles:
• Maintain a clean and hygienic manufacturing areas.
• Control environmental conditions to prevent cross contamination between food products.
•
• Validate all critical control points (CCPs) to ensure the end product safety and consistency.
• Control manufacturing process, and evaluate/validate any process change.
• Write production instructions (production sheet) clearly and record each process step data during manufacturing (good docu-
mentation practice).
• Minimize the risk of contamination during distribution and shipping of food products.
• Establish a system for quick recall in the case of any unsafe food product distributed for sale.
Sanitation standard operation procedures (SSOPs)
SSOPs must be followed to ensure adequate cleaning of both product contact and non-product contact surfaces. SSOPs cover raw
materials, equipment’s, personnel, personal hygiene, and food products handler practice [9]. Food HACCP plans require SSOPs to be
documented and periodically reviewed. This periodically review of SSOPs must be done by professional and responsible management.
In summary standard SSOPs guidelines are:
•
• Hazardous or sensitive raw materials for contamination must be stored separately from other raw materials at proper tempera-
ture to avoid cross contamination.
• Gloves and hair restraints must available for food operators and handlers.
• Food operators and handlers must have permit available for inspection at any time.
• Food operators or handlers suspected of being ill should not allow to work in food contact facilities.
• Proper hand washing facilities are available in food production sites and must be used.
• Selection of proper sanitizer and developing effective sanitation protocol for operators to follow.
• Equipment’s, utensils, and work surfaces must be cleaned and sanitized periodically.

These necessary upfront six steps are:
1. Assemble the HACCP team:
2. Describe the product: Provides the selected team with general description of the product, ingredients, process methods, and
distribution method (refrigerated, frozen, or ambient temperature).

Discussion
Foodborne illnesses are usually infectious or toxic in nature and caused by microbial pathogens (bacteria, mold, viruses, and para-
sites), secreted microbial toxins, chemicals substances, or heavy metals entering the body through contaminated food or water. Microbial
pathogens or its toxins in contaminated food can cause severe diarrhea or debilitating microbial infections including meningitis [10].
Chemicals [11] and heavy metals [12] in contaminated food can lead to poisoning and long-term diseases such as cancer. It is estimated
year. It is important to highlight that children under 5 years of age are more susceptible to foodborne illness and death than adults.
Hazard Analysis and Critical Control Points (HACCP) was originated in the early 1960’s when the U.S. Pillsbury Food Company de-
veloped for National Aeronautics and Space Administration (NASA) HACCP plan system for their space program to produce the safest
addressed through analysis and control of biological, chemical, heavy metals, and physical hazards in raw materials, or interred during
manufacturing process, distribution, retails and foods consumption. Physical hazards in foods are foreign objects such as broken glass, or
metal fragments that can cause harm to the consumer when food contaminated with these foreign objects is consumed.
The seven principles of HACCP system (Identify hazard analysis accessing les risk, Identifying Critical control points, establishing
and records keeping) are currently implemented successfully worldwide in food industries, distribution facilities, retail operations and
in food service stores.
Good manufacture practice (GMP) provide guidance for manufacturing, sanitation, testing methods and quality assurance for a food
operation in order to assist in reducing the risk of foodborne illness and to secure the production and distribution of safe foods for hu-
man consumption. Many countries follow GMP procedures and have created their own GMP guidelines which corresponded to their own
legislations. These developed GMP guidelines are the essential foundation for the development of successful HACCP plans.
Currently implementing HACCP plan in small food business specially in developed nations are limited due the cost and it is the sub-

Consumers are also responsible for their own food safety by following proper storage, cooking of purchased food [15]. In addition,
there are regulatory steps that must be taken by consumers to prevent the contamination and growth of foodborne pathogens in pur-
chased foods to ensure their own food safety. Steps that are must be taken by consumers at home are HACCP like practice.
These HACCP like practice are:
• Wash hand and sanitize food-contact surface often.
• Keep raw meat, poultry, eggs, and seafood’s away from ready to-eat foods.
•
•
• Refrigerate foods properly (cold temperatures slow the growth of foodborne pathogens).
Conclusion
Management awareness and commitment to food safety is necessary for the implementation of an effective HACCP plan (Figure 3).
Implemented HACCP system for a food facility should be reviewed on continuous basis as scheduled, and when appropriate amendments
made is necessary. It is the responsibility of food processors, retails, and distributors to ensure food produced is safe for human consump-
tion. Also, consumers are responsible for their own food safety by following proper protocols at home to eliminate the contamination of
purchase foods.
