I recently posted the following in another discussion, probably better suited to go here, a discussion that is specifically about this product. Unfortunately it appears that I now have to eat my own words, and stand corrected in my previous quality reviews. I can't stand behind a product where an accredited lab demonstrates one thing, while the manufacturer says another.

Just for the record I have no issue with ethoxyquin being used in fish food, but I don't expect to see elevated levels such as shown in that lab report (over 300 ppm!), and I most certainly don't expect to have
any ethoxyquin in a food that is advertised as being *ethoxyquin free*. Keep in mind that this is a food that I have also fed to my own fish, and a food that I have said positive things about on this forum and others, so not really happy about this outcome. In my personal opinion, the lab results that I have seen appear to be genuine.
I have been feeding Northfin for a couple years now, experimented with it exclusively in some tanks. My results were positive. My issue with NF, and for me it's a pretty big issue, is that the company has made some pretty bold statements regarding their use of ethoxyquin, or any form of preservative.
From their website:
"NorthFin Premium Fish Foods does not use any preservatives or harmful chemicals to preserve its product line.
The combination of certain ingredients/vitamins, along with the drying process itself allows the foods to be naturally preserved."

For myself, that just isn't logical. Sans preservatives, fish food will soon go rancid, and most certainly won't have a shelf life of 2-3 yrs, so WTF?
Now I had only my common sense, many years of experience in this field, and scientific logic to go by, until a few months back when I stumbled upon some lab results posted online by an interested party.
Not only does NF apparently use preservatives, they are apparently using ethoxyquin, and apparently at rather elevated levels. Levels that I believe in the product shown in the lab report above was more than double the AAFCO recommended maximum of 150 ppm.
Whoa! I have seen other reports as well, since removed from some website owners that were concerned about legal backlash. Kmuda from Oscar forum promised to send in his own samples, yet thus far I haven't seen those results.
Perhaps Darius from Northfin will pop in to explain how such high levels of ethoxyquin are showing up in a food that is marketed by his company as being preservative free, and ethoxyquin free.
