If you’re teaching food science to middle or high school students, you’ve probably come across the terms HACCP and HARPC. These food safety systems might sound intimidating at first, but breaking them down into simple concepts will help students see their importance in keeping food safe from farm to fork.
So, let’s dive into what HACCP and HARPC are, how they work, and the key similarities and differences between the two.
What is HACCP?
HACCP stands for Hazard Analysis and Critical Control Points. It’s a systematic approach to identifying and controlling food safety hazards in the food production process. The goal of HACCP is to prevent, eliminate, or reduce risks related to biological, chemical, and physical hazards that could make food unsafe to eat.
HACCP was originally developed for NASA in the 1960s to ensure that astronauts had safe food in space (because no one wants food poisoning in zero gravity!). It has since become a global standard for food safety in the industry.
The 7 Principles of HACCP
HACCP is built on seven principles that food manufacturers follow to keep food safe:
- Conduct a hazard analysis – Identify potential hazards in the food production process.
- Determine critical control points (CCPs) – Find points in the process where a hazard can be prevented or controlled.
- Establish critical limits – Set specific limits (e.g., temperature, pH) that must be met to prevent hazards.
- Monitor the critical control points – Regularly check that safety measures are working.
- Establish corrective actions – Have a plan to fix problems if a critical limit is not met.
- Verify that the system is working – Ensure the HACCP plan is effective through testing and record review.
- Keep records and documentation – Maintain records of food safety practices and monitoring.
HACCP is required for meat, poultry, seafood, juice, and canned food manufacturers in the U.S. under FDA and USDA regulations. Many restaurants and foodservice operations also use HACCP-based procedures.

What is HARPC?
HARPC stands for Hazard Analysis and Risk-Based Preventive Controls. It was introduced as part of the Food Safety Modernization Act (FSMA) in 2011 and is required by the FDA for most food manufacturers.
Like HACCP, HARPC aims to prevent food safety hazards, but it takes a broader approach. While HACCP focuses mainly on critical control points (CCPs), HARPC looks at all possible risks and how to prevent them at different stages of food production.
Key Features of HARPC:
- Broader Hazard Control: HARPC identifies and controls biological, chemical, radiological, physical, and intentional adulteration hazards.
- Preventive Approach: Unlike HACCP, which focuses on critical control points, HARPC emphasizes preventive controls throughout the entire food production process.
- Wider Applicability: HARPC applies to a broader range of food facilities, including many that were not previously required to implement a HACCP plan.
Similarities Between HACCP and HARPC
At first glance, HACCP and HARPC might seem like two different food safety plans, but they share many similarities. Both systems focus on preventing food safety hazards rather than reacting to them after they occur. They each require a hazard analysis to identify risks in food production and emphasize the importance of monitoring, corrective actions, and record-keeping to ensure food safety. Ultimately, both HACCP and HARPC aim to protect consumers from unsafe food by implementing controls to manage potential risks throughout the production process.
What’s the Difference?
Here’s a simple breakdown to help your students see the key differences:
| Feature | HACCP | HARPC |
|---|---|---|
| Focus | Critical control points (CCPs) | All risks and preventive controls |
| Regulated by | FDA (seafood, juice, and canned food) and USDA (for meat & poultry) | FDA (for most food facilities under FSMA) |
| Scope | Used mainly in specific industries | Applies to almost all food manufacturers |
| Hazards Considered | Biological, chemical, and physical hazards | Biological, chemical, physical, radiological, and intentional adulteration |
| Updates Required? | Updates are made once a year or when changes relate to a CCP | A more dynamic system requiring more frequent reviews of all preventive controls |
| Preventive Controls | “Prerequisite programs” to control non-critical hazards must be established before implementing HACCP | “Prerequisite programs” are integrated rather than separate |
Teaching HACCP and HARPC to Students
To make HACCP and HARPC engaging for students, incorporating real-world examples can be highly effective. Have students think about potential hazards in a school cafeteria or restaurant setting to help them relate food safety concepts to everyday experiences. Another approach is to create a mini-HACCP plan where students analyze a simple food process, such as making a sandwich, and identify potential hazards and control points. Exploring real-life food recalls can also be valuable; students can examine recent recalls and discuss how HACCP or HARPC measures might have prevented them. Additionally, role-playing food safety inspectors in a mock food production setup can provide a hands-on way for students to identify risks and understand the importance of food safety regulations.
Wrapping Up
Both HACCP and HARPC are essential tools in modern food safety, helping keep our food supply safe from contamination. While HACCP has been around for decades and focuses on critical control points, HARPC is a newer, broader system that applies to more food facilities.
By teaching these concepts in a fun and interactive way, you can help students connect classroom learning to real-world food safety—and who knows? Maybe they’ll be inspired to pursue a career in food science or food safety!
