Em geral, os Ferengi são principalmente consumidores de pequenos insetos:
Traditional Ferengi cuisine consisted largely of slugs, insects, grubs, and other creatures Humans would call "bugs". Many partook in the beetle snuff habit, snorting a fine powder of dried beetles. In one instance, Jake Sisko told Nog that he was helping his girlfriend who was studying to become an entomologist, to which Nog replied "What's an entomologist?" Jake explained that it was "someone who studies bugs." Nog, misunderstanding the science, replied "Ohhh!, she wants to become a chef!" However, only native bugs were considered edible, and foreign (off-planet) bugs are treated with disdain. (DS9: "Sanctuary")
De acordo com o artigo da Memória Alfa no Encontro no Farpoint em Apocrypha:
When Groppler Zorn threatened to give access to Farpoint Station to the Ferengi Alliance, Picard remarked that he hopes the Ferengi find Zorn as tasty as they did their past associates. The novel The Buried Age establishes that the Ferengi's early reputation as a dangerous race was merely propaganda established by Zek because the Ferengi, after hearing early reports about the Federation and their moneyless economy, decided that the Federation might well be insane if they truly did not seek profit. Zek also threw funding into a large military buildup in order to preserve their appearance as a dangerous race and in order to defend themselves against the Federation, should it prove necessary.
Isso provavelmente foi feito porque o desenvolvimento da raça Ferengi os retratou como decididamente não o tipo de espécie que comeria seres sencientes.
