Should the only worms be bait......

While preparing fresh fish, espcially scrod, it is not uncommon to find thin worms that are still wiggling when removed from the meat. My fish supplier assures me that this is not a sign of poor quality. I was told that some fish are "candelled" for worms. Should this be of any concern, and what other types of fish are known to have these?

From personal experience, I have found that fish that come from warmer waters tend to be more inclined to have parisites than cold water fish. As far as I know the worms you describe are not harmful in cooked fish (Im not sure about raw fish), but not something you really want your guest to find. Hopefully someone will have a more definative answer for you.

Did you say worms????? Our fish doesn't have any worms.....ok not true, some fish do have worms. Let's address the questions. What fish have worms.......it does not seem to matter, warm or cold water, some fish have worms. Worm candidates are, sword, grouper, sole, cod, and amberjack. Cod and sole are "candled". The fish is put on a glass over a flourescent light source and the parasites are pulled. If you consistently find parasites in cod or sole, your supplier is buying from a less expensive source.....tell them thanks for saving me money but did I have to give up the quality.

They tell you that for cooked fish the worms won't hurt you.....but if I get a fillet full of worms I'm not eating it......save em for bait...
