Results Found

ChemSee has tested many commercially available foods for the presence of Formaldehyde.  Tests have been ran in duplicates, as well as on different batches of the same fish.  A portion of the results from API’s tests can be found below.

It was found that many of the fish imported from other countries such as China, Indonesia and Vietnam have much higher levels of Formaldehyde than what is naturally present in fish.  This may indicate intentional adulteration to increase the food’s shelf-life.
