I tried to stress the fact that it is
fish meal in several of my posts so as to avoid this confusion.......

.....The other products not using fish meal in the ingredients list are most likely fine ......
It could include salmon meal , ocean fish meal, etc. etc. You would have to ask the manufacturer if the
supplier put it on too....
This is the quote I've included to try and clarify any confusion.....
"Fish meals, NOT fish ingredients are a concern with ethoxyquin. As example, ‘salmon’ listed on a pet food label would not be an ethoxyquin preserved ingredient; ‘salmon meal’ might be. The ONLY way to know is to ask the manufacturer specifically. Warning however, some responses I have received did not directly answer my ethoxyquin question. As example, one manufacturer told me “we do not add ethoxyquin to any of our pet foods”. This response does NOT tell me if their supplier might add
ethoxyquin. I am waiting for their follow up response."
Yes it is amazing that some pets are more susceptible to the vast amount of toxins they're exposed to and some seem to be able to handle them....
....
Reactivity to chemicals in a population is similar to other population statistics and is represented by a bell-shaped curve. In other words, at one end of the spectrum are sensitive individuals, and at the opposite end are resistant individuals; these groups are relatively small compared to the vast middle group, who show varying degrees of susceptibility – but who are all susceptible. Thus the sensitive group – dogs who have displayed signs of toxicity – happen to be the sentinels for the younger, healthier ones who will eventually be affected; it’s just a matter of time.
