Kmuda ........ SA suppliers of fish meal and fish oil are already using Naturox.

From the Kemin website, the manufacturer of Naturox;
Kemin began selling in Brazil in 1999 and opened our regional headquarters in Indaiatuba in 2004. In addition, we have a location in Chapeco, Vargaeo, Buenos Aires, and sales representation throughout the region to best serve South America.
The current level of EQ required to be present at the time of shipping is 100 ppm.
The International Maritime Organisation (IMO) regulates shipping safety and requires that fishmeal is dosed with ethoxyquin at between 400 ppm and 1000 ppm
within 12 months of shipping, ensuring that at least a level of 100 ppm is present at the time of loading before shipping to mitigate the risk of combustion during transport at sea.
The IFFO tests that I previously posted, demonstrate that even at 50 ppm, EQ will be safe to transport in ships, for up to 12 months, and beyond. Naturox at an inclusion rate of 250 ppm will offer the same safety towards spontaneous combustion. I posted that info because as far as I know, that is some of the only data available on Naturox, and it's safety factor for fire on ships - over a 6-12 month duration.
No one should be shipping containers of fish meal that contain 1,000 ppm of EQ, when they leave the port in SA. If they did then the residual EQ level in krill meal and fish meal entering the pet trade would be uber high, and fish food would typically be far higher than what you are going to see in your lab reports. Which I will state again, will for the most part be under 100 ppm. I suspect most will fall into the 50-75 ppm range.
Personally I have no issue with 50-100 ppm of EQ in my pet fish food. Even 150 ppm, the maximum allowed, would not send me over the deep end. But 300+ ppm, as seen in the one lab report posted here, was a bit shocking, and most certainly isn't something that I support. I also don't support manufacturers that lie to their customers.
