I don't think so. You can disagree that there's 'real' zombies in Cannibal Apocalypse, so that you wouldn't call it a zombie movie (I disagree), but the movies from the exploitation cannibal genre are about cannibalistic tribes in rainforests, not infected people in a city.
I’m not ‘trolling’, Wayne, but I disagree with this – imo, it’s quite reductive (note the smiley:

) Like Tanzi said, those films are what could be labelled jungle adventure films (I usually use the label ‘jungle exploitation’ to describe them), like Cornel Wilde’s THE NAKED PREY before them, which have cannibalism as a key theme – this is especially true of the first films in this cycle (MAN FROM DEEP RIVER, JUNGLE HOLOCAUST), whereas the later films, actually quite a short-lived series, foregrounded the cannibalism aspect (CANNIBAL HOLOCAUST, CANNIBAL FEROX).
What makes APOCALYPSE different (and, imo, preferable) is the way it pulls together disparate elements from popular genres of the time – the cannibal film, the urban zombie film, the Italian war film. These diverse influences are present in the alternate titles for the film: APOCALYPSE DOMANI, CANNIBALS IN THE STREETS, ASPHALT-KANNIBALEN. I also like the fact that where the jungle exploitation films all focus on indigenous people who are cannibals (which makes many of them quite reactionary, at least on the surface) APOCALYPSE features American GIs who return home to find that they have a lust for flesh-eating. The (gorgeous) US one-sheet communicates this well, I think:

And, for me, this is all on-topic because bringing together all of these different subgenres gives APOCALYPSE an added depth that most of the jungle exploitation films lack (imo): like Bob Clark’s DEATH DREAM, you can take this as a film that uses cannibalism as a metaphor for the effects of Agent Orange, or what we now call PTSD – or not, if you prefer. (Incidentally, my favourite of the jungle exploitation films is Deodato’s INFERNO IN DIRETTA/CUT & RUN, which also shows the limits of the ‘jungle setting = cannibalism’, and vice versa ‘cannibalism = jungle setting’ associations.)
I’d love to see this one (and CUT & RUN) hit Blu sometime soon.
But yep, even though I don't agree with your restricted definition of what constitutes a 'cannibal film', I can respect it - so please don't think I'm 'having a go' at you
