Good Day everyone, 

 

I recently had a customer call in regards to finding dirt particles at the bottom of their plate. They used a marinate. I am trying to find the culprit. I have narrowed it down to two ground ingredients which are predominate in the product, garlic and onion. I know both are ground spice, I ran a filth test. What test can I do on the product or suspected RM?

Am I approaching this the wrong way? I have gone through our sanitation documents which showed we washed the machine prior to filling, followed by an atp test.

First and formost, did you see the picture/got sent back the product from this customer that is complaining? Have you made sure it is "dirt" and not something else?

The customer used up all of the product therefore could not send it back. I pulled a bottle from the lot and it is currently in the lab. It is just deciding what test to have the lab do.
