So there seems to be mercury in many samples of corn syrup. From what I understand we are talking “parts per trillion” which is pretty small. However I don’t like corn syrup anyways and would rather use sugar, so just more reason to avoid the stuff. For comparison when they talk about mercury in fish they talk “parts per billion”.

Here is my favorite explanation on the corn syrup mercury from Consumer Reports. And here are the links to the studies.

I also enjoyed their piece on mercury in tuna.
