Validation and Verification

How to develop your product testing requirements

Product testing is an integral part of your food safety management system and serves to verify that your food business is producing food safely. In this post find out what you should include in your product testing documentation along with how to determine the testing limits for common microbiological and chemical contaminates.

Product Testing Elements

If your business is certified to an GFSI recognised standard, checking the standard for requirements is you first port of call. If not, at a minimum, your product testing requirements should include:

  • Testing Required – For example Water quality, Environmental Swabbing, Sensory, Microbiological, Chemical
  • A summary of why the testing is being performed
  • The location of where the testing will take place
  • The frequency the product testing will occur
  • The name of the provider – this is the person who will complete the testing analysis. This may be an external facility or your own in-house laboratory if you have one.
  • The test method to be used. Try and tie this back to an international or recognised testing standard if possible.
  • The test limits – these determine the parameters of compliance. For example, Listeria species is Not Detected per 25g, Bacillus cereus  < 100 cfu/g
  • Corrective Action – If a result shows a non-conformance against the product testing limit, detail what will be done to rectify the issue.

Keep with Legal Limits

Depending on where you are located, there may be legal test limits that apply to the products that you produce. You will need to do a little bit of research of your local food laws to see what they are. Here is a great resource published in September 2018 to get you started. It also provides plenty of international links to point you in the right direction.

Food Standards Australia New Zealand – Compendium of Microbiological Criteria for Food

You can also refer to your preferred external testing laboratory to provide guidance on acceptable limits for microbiological, pesticide, heavy metal or other chemical contaminates.

Documenting you Product Testing Requirements

For my consultancy clients, I tend to use an excel spreadsheet to document the product testing requirements. I also tend to incorporate other system testing that is required by the business which can include internal audits, GMP audits, mock recalls etc.

Label each of the columns with a different product testing element (as listed above). You can see an example below.
