One can discuss the naturally occurring levels, but I think it is a fact that butyric acid is found in honey and many other foods.  

>The acids from clover honey were isolated by ion-exchange adsorption and separated by silicic acid partition chromatography and ion-exchange chromatography. The different acids were identified by paper chromatography with six solvent systems, infrared spectra of the sodium salts, and derivatives. Acids definitely identified were butyric, acetic, formic, lactic, succinic, pyroglutamic, malic, citric, and gluconic.
