Question: are vinegar eels in all vinegar?
Answer: Vinegar eels are actually not eels at all, but a type of roundworm. Turbatrix aceti is a non-parasitic nematode commonly found in raw (unpasteurized) vinegar. They look like tiny worms, about 1/16 inch or 2 mm in length. FUN FACT: Vinegar eels are actually bred as a supplementary food for fish!
