Establishment of the HACCP Plan in a Catering Plant

In this study, HACCP (Hazard Analysis Critical Control Point) plan was set up in a catering plant which   had a  capacity of 2000 persons/day and 40 employees. Founded HACCP system consisted of the following   seven principles: (1) Conducting a hazard analysis, (2) determining the Critical Control Points (CCPs), (3)   establishing  critical  limit(s),  (4)  establishing  a  system  to  monitor  control  of  the  CCP,  (5)  establishing  the   corrective  action  to  be  taken  when  monitoring  indicates  that  a  particular  CCP  is  not  under  control,  (6)   establishing   the   procedures  for   verification   that   the   HACCP   system   is   working   effectively   and   (7)   documentation of all procedures and records appropriate to these principles and their application.         That  action  was  carried  out  by  following  this  diagram:  (1)  Assembling  HACCP  team,  (2)  describing   terms   and   intention,   (3)   describe   product,   (4)   identifying   intended   use   and   consumer   category,   (5)   constructing the flow diagram, (6) on-site confirmation of flow diagram, (7) listing all potential hazards and   considering control measures, (8) determining CCPs,  (9) establishing a monitoring system and critical limits   for  each  CCP,  (10)  establishing  the  corrective  actions,  (11)  keeping  record  procedure,  (12)  establishing   verification procedures and, (13) revision of HACCP implementation.

Recontamination Issues in the Food Processing Industry What, Where, and How Important are They? ( Dr. Paul A. Hall )

Producing Safe Food is Our Top Priority!

• Consumer protection and trust

– Consumers must be able to trust the brands they buy and the food they

– Food safety is absolutely critical to that trust

• Business survival/self-interest

– Our brands are our most important asset

– History is replete with brands and businesses being destroyed because

• Industry responsibility

– Moral obligation to produce food as safe as practical

– Industry pledge not to make safety a competitive issue eat of a lapse in food safety

Why is Food Safety our Top Priority?

• It is a cost of doing business

• The changing global food safety landscape demands more diligence, flexibility, and speed than ever before.

• The cost impact of not doing food safety right is higher than it’s ever been.

• The benefits of doing food safety right contributes directly to the bottom line – and not just in cost avoidance.

• Consumer and regulatory scrutiny are at an all time high.

• World class companies that win in the marketplace have world class food safety principles.

Causes of Foodborne Contamination

• Food Products can become contaminated via several routes:

– Naturally occurring (raw foods)

– Underprocessing/improper processing

– Recontamination/cross-contamination

• Pathogens

• Spoilage organisms

• Allergens

• Chemical contaminants

– Intentional contamination

• Economic adulteration (e.g melamine)

• Bioterrorism
