How Critical is Petfood Safety? The Short Answer Is Very Critical.
HACCP is a widely accepted method for controlling hazards
that is employed within many food safety management systems.

As your investigation begins, you will most likely find a few common systems—for example, SQF (Safe Quality Food), BRC (British Retail Consortium) and ISO (International Organization for Standardization). Selecting and developing the correct type of system and HACCP plan for your market and products is as critical as the plan itself.

At the time of this publication, a specific and documented legislative rule-set regarding use of HACCP in the US has yet to be developed for petfood. What we do see are petfood producers adopting existing formats as required by 9 CFR Part 417 (Code of Federal Regulations) for the human food industry.

Within these formats, developing and implementing a HACCP plan can be broken down to a very basic set of steps (also called principles).

7 principles of HACCP
Whether you call them steps or principles, the key components should be the same for every HACCP plan:
Step 1. Analyze the process for potential hazards
This step has three key stages:
1. List all potential hazards.
Look at every component and step of your operations, including but not necessarily limited to:
2. Evaluate all potential hazards for severity and likelihood of occurrence.
Severity. Consider the seriousness of the effect and:
Likelihood of occurrence. If not properly controlled, how likely is the hazard to have an effect in these areas:
3. Determine if each hazard needs to be addressed in the HACCP plan.
Likelihood of occurrence. If not properly controlled, how likely is the hazard to have an effect in these areas:
Step 2. Identify critical control points (CCPs)

If deemed significant—passing all the criteria specified in step 1—a hazard must be controlled by a CCP. The point in a process that is the last step at which a control measure can be applied and that is essential to prevent or eliminate a specific food safety hazard or reduce it to an acceptable level is the CCP for that hazard or process.

Remember, a CCP defines the type of hazard and the process location. A regular, non-critical control point in a process is typically not safety related but rather about maintaining quality or regulatory compliance. A critical control point is about safety. Examples could include measures such as:

A proper HACCP plan should end up with only about five CCPS. If you have more, they likely are not all critical—i.e., safety related. By choosing a small number of CCPs, you can concentrate your resources in the places where they have the strongest impact. This is the essence of HACCP.
Tip Check 9 CFR Part 417 (Code of Federal Regulations) for what FDA requires in human food HACCP plans.
Step 3. Establish a critical limit for each CCP

What is the operational reference point that guarantees the hazard has been identified and killed or removed from the process? That is a critical limit: the maximum and/or minimum value to which a biological, chemical or physical parameter must be controlled.

Basically, a critical limit establishes the absolute limit between safe vs. unsafe. So in identifying these, you want to look at food safety limits, not operational ones. Focus on studies done in your own plant or others. Other sources of data include:

Step 4. Establish CCP monitoring procedures

Formally this step is defined, according to NACMCF (1997), as conducting a planned sequence of observations or measurements to assess whether a CCP is under control and to produce an accurate record for future use in verification.

The only way to ensure CCPs are working is to constantly monitor them. Loss of control must be identified as soon as possible. Be sure your procedures include the “four W’s plus H”: who, what, when, where and how to monitor.

One of the more common mistakes with this principle is the “when,” particularly when the monitoring is not continuous or is periodic. Some basic points to consider include:

Tip NACMCF (1997) has helpful definitions and information, including about critical control points monitoring and corrective actions.
Step 5. Develop corrective actions

What do you do if an issue arises—a CCP falls out of control? As mentioned on page 4, petfood safety is not yet regulated in the US, but any rules put into place by the Food and Drug Administration (FDA) will likely follow human food regulations. For example, FDA requires documented corrective actions (CAs) in food HACCP plans.

At the least, per NACMCF (1997), the CA procedures outlined in the HACCP plan should:

For human food, FDA requirements are exhaustive and can be onerous. For example, according to 9 CFR 417.3 (Corrective Actions) the HACCP plan shall describe the corrective actions to be taken, and assign responsibility for taking corrective actions, to ensure:
Step 6. Establish verification procedures
Verification should be ongoing and answer this basic question: “Are we getting it right?” Your procedures should address two issues:
Tip 9 CFR 417.3 outlines the exhaustive FDA requirements for corrective actions in human food HACCP plans.

Step 7. Develop recordkeeping procedures
This is fairly straightforward: You need written documentation that the HACCP plan is being carried out. The documentation should include all activities and discussions that have occurred during the first six steps and all ongoing activities and decisions within the HACCP plan. Many good examples and tools for documentation already exist. For ideas, look to:
Be proactive.

Again, it is important to remember that currently there is no legislation for safety in the petfood processing industry. FDA simply states now that petfood suppliers must produce Salmonella-free products.

If FDA puts petfood rules in place, it will most likely copy the protocols set up for the human food industry. For example, with food, testing of all CCPs must be tested and verified by a thirdparty laboratory, outside the production facility. While the samples are being tested by this third party, the product cannot be distributed or sold. Think of the warehousing and logistic challenges that can arise.

It is up to petfood producers to develop their own strategy or system. If they don’t, FDA most certainly will.
