Great investigation! 

So I got curious and looked up the address of Global Food and found that their listed address is the EXACT same as the Roastery Coast nuts, the original product that I found the Global Food Gluten Free Certification on. Global Food and Roastery Coast are the same company. I'm seriously cracking up at how sketchy it is.  ROASTERY COAST OFFICE 40222 La Quinta LN B102  Palmdale, CA 93551   Global Food Office Address: 40222 La Quinta LN, STE B-102Palmdale, CA 93551   Business Hours: Monday - Friday: 8:30am to 5:00pm   Telephone: 661-977-2300   Email: info@globalfoodcert.org

The only good part I see in their response is the gluten free facility.

Yeah, it's just a marketing ploy.

Agreed on grammar. I'm not the best in that department, but their response quality definitely raised some red flags. Below is my response to them, not that it'll do any good.   "It seems your certification is basically a general gluten free statement with FDA 20ppm limit masked behind the word "certified". Manufacturers should not be the ones doing the testing of their own products, that is a conflict of interest. If your company truly wants a certification that sets a high quality standard, a 3rd party would be doing that testing, as well as setting a stricter ppm. Just because a food is naturally gluten free, does not mean it is inherently low risk for gluten cross contact (oats are an example)."
