Proficiency Testing Requirement for SQF Certification
Hello all!
We recently had our first (brutal) SQF certification. We passed(!) but are now working on our non-conformances.
We were dinged on lab proficiency testing. We do not perform any micro testing, etc, only basic physical and chemical analysis not related to food safety. The guidance confuses me because it states 'critical to food safety.' Is this something I can argue?
I appreciate this forum's help as it has been a life-saver working towards preparation and correcting the non-conformances. There just much available for clarification out there.
Thanks!
You've got 2 separate sections of the code confused--you rightly got dinged because proficiency testing is required for ALL internal lab testing
2.4.4.2 Product analyses shall be conducted to nationally recognized methods or company requirements, or alternative methods that are validated as equivalent to the nationally recognized methods.
Where internal laboratories are used to conduct input, environmental, or product analyses, sampling and testing methods shall be in accordance with the applicable requirements of ISO/IEC 17025, including annual proficiency testing for staff conducting analyses.
External laboratories shall be accredited to ISO/IEC 17025, or an equivalent international standard, and included on the site’s contract service specifications list (refer to 2.3.2.11).
2.4.4.3 On-site laboratories conducting chemical and microbiological analyses that may pose a risk to product safety shall be located separate from any food processing or handling activity and designed to limit access only to authorized personnel.
Signage shall be displayed identifying the laboratory area as a restricted area,
accessible only by authorized personnel.
Scampi beat me to it!
Just curious however. What do you mean by brutal?
I think you need to expand on what testing you go dinged for. It might be worth asking about. The SQFI guidance document indicates the proficiency testing is not for product quality or sensory if you are using the food safety standard.

Hi Quality_AF,
Micro proficiency testing isn’t specifically mentioned the SQF Code, it requires testing methods to be in accordance with the applicable requirements of ISO/IEC 17025, including annual proficiency testing for staff conducting analyses. If you don’t do micro and you don’t have a test method, I don’t see how you can be pulled up on a lack of micro proficiency testing.
As per kingstudruler1’s post, you need to clarify the wording of the non-conformance, the types of products and who is doing your micro testing? With that information I am sure you will get greater clarity from posters.
Kind regards,
Tony
It was brutal because we were not as prepared as we thought we were, the Code (SQF 9 - Pet Food) contradicts the checklist (EMP is mandatory in the checklist but not in the Code), and the auditor constantly interrupted me.
Non-conformance: 2.4.4.2 The site’s onsite lab conducts finished product testing but does not participate in any applicable proficiency testing program.
We were under the impression that because we do not perform micro testing we would not be required to conform to this clause. We blend antioxidants used in pet food. We test internally for some physical properties (viscosity, specific gravity, and amount of active ingredients) however, any micro testing is sent to a 3rd party laboratory.
My confusion with this comes from wording in the guidance document: "This means that a site that conducts laboratory tests, critical to food safety, is required to verify the accuracy and reliability of the testing methods used on site through a proficiency test."

OP specifically said NOT micro
"We do not perform any micro testing, etc, only basic physical and chemical analysis not related to food safety. "
Sometimes the language used in SOP's or just statements to the auditor can cause confusion leading to a finding. My first ever SQF at the spice place, we almost got in trouble for calling a room our "Lab", when all we did was use a rotap machine to test for product yield at different sizes. Auditor heard "lab" and started really digging for a few minutes, and our consultant quickly figured out what he was going for and had to help us clarify the exact point that none of the testing is for food safety.
That said, we were still required to show sufficient training for anyone involved in rotapping for yield analysis, as it had bearing on the specification for the finished product. They had to be sufficiently trained on our sampling procedure, testing frequencies, calibration of the rotap, proper use of the rotap, etc. Even where OP's testing is not for food safety purposes, they still can be hit with a finding if they're not proving the proficiency of staff performing these non-food safety related tests.

I have seen alot of confusion on this clause. The guidance does seem to differ from the standard. However, you are not audited to the guidance, but the standard. I did have one auditor tell me that the scope of the audit is food safety (not quality) which is why quality type testing does not need to meet proficiency testing standard. You obviously found an auditor with a different opinion.
I think it would be wise to have the CB clarify. I think they might be your best source of reliable / repeatable source of info for your situation.
Or, just apply the standard to all of your testing and be done with it. More work, but eliminates being subjected to differing opinions in the future.

Could 'proficiency training' be completed in house? I have training records but I don't think they were reviewed.

I did reach out to the CB for clarification; when asked if it mattered the type of testing completed they replied "it does not sound like that matters".

2.4.4.2 states "nationally recognized methods or company requirements," so I believe and would defend training my in-house employees to in-house procedures to run non-food safety tests.
In my case of the rotap, I had to be able to prove employees knew how to calibrate it and then properly record the results. "Calibrate" applied loosely here, there's a little arm that smacks the trays to filter the material, and the manufacturer's book stated it has to be x number of mm at the top of it's up and down stroke.
If you're using any machines for the in-house quality analysis, they need to be trained that the machines are functioning within specified parameters (calibrating them can be left to maintenance so long as the employees know what to check). If they weigh samples for this analysis, training on how and how often to calibrate that scale would need to be included. So on, so forth. I only read "physical and chemical analysis," so whatever that entails you need to be able to prove they're trained to do that task and properly use whatever equipment (including what to do if the measurement isn't within spec).

Concentration of metabolically active ingredients for dietary supplement/additive in feed sounds like safety to me. "not safety related" could be a difficult argument to make.

I understand your point, however our antioxidants are used to inhibit oxidation in the food; it is not used as a dietary supplement.

"We do not perform any micro testing, etc, only basic physical and chemical analysis not related to food safety. "
:uhm: Maybe I'm missing something here Scampi?
It doesn't help that you snipped the quote to take my post out of context as I asked for wording of the NC.
Quality_AF has now clarified that the NC is because the site does not participate in any applicable proficiency testing program.
Kind regards,
Tony

Hi Quality_AF,
Proficiency testing can be carried out in-house by a collaboration of laboratories getting together and comparing results based on analysing a sample split between them (i.e. the same sample) by the same recognised test method. I would normally expect at least one of the laboratories to have ISO/IEC 17025 or for the split sample to be analysed by a third party ISO/IEC 17025 accredited laboratory as well.

The test method is what concerns me. We use internally developed methods; as do the ISO accredited laboratories I have found that test for these active ingredients.
Can it be as simple as testing in-house, sending samples off to an ISO accredited laboratory, then comparing results?
I'm curious if anyone has an example of proficiency testing for testing OTHER THAN pathogens testing.

Yes, I would do just as you stated. Send a sample to the certifed 17025 lab and have it tested (or use retains if you have them). Then have your employees test the sample. Compare results. You will need to develope pass / fail crtiteria (X% +/-, etc) . Designate / document the employee as proficient or not. Develope corrective actions as needed. Repeat at the frequency that you determine.
There are some items I havent used a third party lab for, but just compared results between personnel. More for organoleptic type items.
Thanks for the help everyone! We have created our program. Now all I need to do is get the 3rd party lab to contact me back about testing.
