How to trend cleaning verification results

Have you ever wanted to implement an easy way to trend cleaning verification results? In a recent audit of one of my clients, the auditor shared the following method that I thought was worth sharing with the HACCP Mentor community. If your business is required to complete this compliance activity keep reading to find out how.

The purpose of trending

Your business may be required to trend cleaning verification results as a part of your external HACCP and food safety certification process. If you are certificated to a GFSI recognized standard, then this will certainly be the case. The compliance aspects aside, trending helps us to determine if a process is becoming or trending ‘out-of-control’.

In this case, we would be able to determine if there is an adverse pattern emerging for the cleaning of key equipment in our food business.

Make it effective and easy

When trending cleaning verification results, the key is to make the reporting of the cleaning status easy to capture. No need to get overly technical here.

Step 1: Inspect the item after it has been cleaned

Step 2: Allocate a ranking to the level of cleanliness

Step 3: Record this result

Here is an example of a simple ranking matrix with an example verification check.

Verifying cleanliness

Tip: When verifying the cleanliness of a piece of machinery or equipment, look at individual points on the equipment or machine rather than the overall machine/equipment cleanliness.

Verify the cleanliness of different points on the machine or equipment

Trend cleaning verification results

If you are using a paper record you will need to log the results in some type of spreadsheet so you can easily see the trend visually over a period of time. You can see an example of this below.

If you use mobile records, the system should be able to generate a trending graph with a click of a button.

    Hi Amanda
    I never thought of trending internal cleaning verification, what I do I swab lines monthly and send results to lab and trend according to those results. it that good enough or I must also trend internally weekly.

      Looks like you are doing fine Nomfundo with your current method. YOu will just need to confirm if the action required as outlined in post is applicable to any 3rd party certification standard that your business gets audited against.

      Hi Jeff, thanks for your question. I would suggest putting together a count-in / count-out check and written procedures for disassembling and reassembling equipment during the cleaning process.
