Food Testing Labs

The labs listed below are a few examples of private accredited labs that will provide pH testing for both home canned foods and homemade chilled foods. Each lab has a website and phone number listed. Prices for pH testing range from $16 to $25 per sample and prices are subject to change.

Proper packing of samples for shipping is important. It is your responsibility to contact the lab to determine packing method, shipping method, and the sample size needed. For example, chilled foods must be packaged and shipped on ice or with gel packs and not frozen.
