Poisoning or toxicity derived from flesh or meat (an extremely rare or theoretical term).
From Greek kreato- (meat) plus toxikon (poison, from toxon 'bow'—poison was originally used on arrows) plus '-ism.' This appears to be a constructed term combining classical morphemes rather than an established medical diagnosis.
This word is almost certainly not used anywhere—it's a theoretical construct following medical Latin, but the fact that someone thought to build it shows English medical terminology works like a construction kit where specialists can generate terms for any hypothetical condition.
