Reducing the Risk of Foodborne Illnesses
The Hazard Analysis Critical Control Plan (HACCP) is a system
used to reduce the risk of foodborne illnesses in the United
States. Preventing problems from occurring is the paramount goal
underlying any HACCP system. The principles employed in the
development of HACCP plans meet the goal of preventing foodborne
illnesses.
In a PowerPoint presentation of 5-10 slides, describe the
history and application of the HACCP system, addressing the
following:
Provide a brief history of HACCP.
Describe the steps involved in the development and
implementation of a HACCP plan.
What are the advantages of using HACCP rather than
traditional food safety programs in retail food establishments?
Describe critical control points and critical limits as they
are used in HACCP programs and what happens when there is a
deviation.
Why is monitoring an important step in the HACCP system?
You are required to use a minimum of three additional
