If you stick with a name brand, you should be okay. Just avoid store brands. Those are made by the lowest bidder and the contracts are let every three or four months. If they screw it up (and they have) what do they care? If (let's pick a target) wally world lost all their store brand pet food business, what have they lost, a half percent of one day's profits? On the other hand, if Purina, Hill's science Diet, Eukanuba, Iams, etc. suffer quality problems and lose business, a lot of guys wearing suits will have to explain a new job search to an angry wife.

I personally tasted Hill's I/D perscription food while touring their Kansas City plant a decade ago. Bland (it's supposed to be), but eminently edible.
That said, in a survival situation, I'd rather eat any pet food than worms and bugs.
