Hazel is the same as the UK Harry Hamster!Petco hasn't updated the ingredients or GA as far as I'm aware,but when you get the food you can verify the ingredients just to be certain
The company was actually really caring and responsive from what I've seen in terms of acknowledging previous use of an unsafe preservative(ethoxyquin I believe)and that due to it being unsafe they no longer use it.It shows a major difference between most companies that would simply try to bury such a thing and never acknowledge it!
It really is much better than any single food in the US,and to get a good enough food otherwise you'd have to mix several foods and then you might end up using a combination that isn't quite enough protein anyways(which I personally do with added flax seed and freeze dried chicken,but it isn't as easy as using just one food).
