In several dictionaries I encountered under abdico (1st conj.):
Abdicare cibum aliquem (Plin.) to prohibit the use of any meat as not good (Thomas Thomasius dictionary)
Abdicare cibum aliqem (Plin. 20, 9) to forbid the use of it (Robert Ainsworth dictionary)
I looked up the reference and I found (Probably the correct one, but not sure):
Democritus in totum ea abdicavit in cibis propter inflationes (Nat. 20, 9)
I assume, maybe wrongly so, that ea matches aliquem in the dictionaries formula, but in cibis here seems to be adverbial, specifically not the expected accusative.
So all in, I can't reconcile those. Can abdico be used with double acc construction? if so what does it mean?
