Title: Parasite free?
Post by: kathy on January 02, 2018, 10:20:08 PM
Please skip the images if you are squeamish like me.
In fact, you may want to skip this entire post.

So for the first time ever I found a live worm in a fish that I was prepping to cook.
The fish was a cabezon taken up in Mendo. I gutted and gilled it before leaving the beach so I could roast it whole. Threw it right in the fridge when I got home and took it out the next night to cook. There was a white strand ~12" long on the fish when I washed it and patted it dry. I pulled it off and to my horror it moved - sluggishly - so I set it aside and washed and inspected the rest of the fish. Didn't see any others so proceeded with the most epic roast: 375 degrees on a glass baking dish - stuffed fish cavity with green and red onions, garlic and cilantro and lime slices - then covered fish with olive oil then crusted it with salt, curry powder, turmeric, ground coriander, lime juice, chili powder. I was paranoid about the worm so I roasted the CRAP out of the fish and read internal temps of 165 at a few thermometer samplings. The meat under the skin was moist and delicious but I did find one other dead worm as I pulled meat off the bones. It was too good not to eat! (The FISH, not the worm!!)

So now I am a little freaked out by the size of this worm and (I have an unfortunate pre-existing terror of parasitic worms thanks to 3 separate incidents from my childhood) generally grossed out and surprised that this is the first time I have seen these. And feeling somewhat crabby that my delicious fish in my head now has this association. Here's the worm as I found it, as it was when I left the kitchen for dinner and came back (it tied itself into a knot) and I could use some perspective here to get out of this worm funk.

How and when are you confident that your cooked fish is safe, when you find worms? How do you remain mentally / emotionally confident about eating your fish (esp if you have a little bit of a parasite phobia)

Thanks
Yuk

I don’t even bother taking blacks anymore for that very reason lol. I like to think gutting the fish as soon as you dispatch it helps to decrease worms in the fillets but that doesn’t always work either.

Hold the fillets up to the light and the worms should show through the meat. I just cut them out while cleaning.

I see them all the time. Blacks can be terrible but they can be in any of them. I rarely eat whole fish for this reason(especially not cabs).

My room mate chewed a mouth full of live worms form a bite of ling he tried to cook on his own but failed.


Contrary to popular belief you cannot “get worms” as they can only survive in your body very briefly.


I just cook them until it’s clearly done and eat without worry. Or freeze for a week and eat raw.
See i always thought these ones you could get, but blacks, perch and cabs seem to be filled, ive seen certain  lings with them too. I just cook thoroughly and try to avoid looking closely at the fillets.  But pull them out when i do see them.

Same here. 

I don’t even tell the wife about worms or she would never eat fish again.  As awesome as it is that so many eat the whole fish I mostly eat fillets and if left in the fridge overnight any worms missed will come to the surface so they can be pulled out. 

The rest goes in to the crab pots or garden.

I always fillet the fish and hold them up to the light. The dark spots are worms. I just dig them out with the fillet knife.

Fish found near seal and sea lion haul out seem to have more worms, but almost all fish have them. If you don’t see them you aren’t looking.

All sushi restaurants in the USA serve previously commercially frozen fish. Commercial freezing is colder than our home freezers. Thoroughly cooking fish kills the worms too.

The most that these worms can do is make you sick, but you’ll pass them in a few days. I prefer to avoid them anyway so I skip the fresh sashimi and ceviche.

I also pass on Blacks and Cabezon.

What others have said is spot-on. The larval nematodes are there, in most fish, especially around concentrations of marine mammals, which is their host in an earlier stage of life. Your home freezer won't kill them, only cooking will (freezing them to -15 degrees F or something like that will kill them but that's commercial territory). I "candle" any fish I eat raw and if there are more than one or two, I'll skip the raw application. These particular worms live in the flesh so how fast they're gutted makes no difference to the likelihood of them showing up.

A home freezer will kill them. Zero degrees for one week is required. Or negative 15 at I tho k 3 days.

Frozen is frozen... they will die in your home freezer, give it a week or so...

But there's a lot of gross stuff in all meat, just don't ask questions. Where do you think that cheap $1 menu gets its meat from... I have friends in the dairy business...  ???

That will work for tapeworm larva but not for the anasakid nematodes, which is what we encounter the most. I could be mistaken but I think those only die at temperatures below what a home freezer is capable of producing.

Speaking of tapeworms, my brother had one once a few years ago, probably from fish. It didn't make him sick but it made for an interesting episode in the bathroom one morning.....

I almost never find them in lings. In fact I'm not sure I ever have. But blacks are full of them. And halibut - especially in the belly area - are notorious for worms.

But like everyone else has said, pick them out when you fillet the fish, and make sure it's cooked through and you're fine. Freezing is good for extra measure.

I've found a couple while cleaning smaller lings, they're probably better at hiding in the larger ones. Hit em with that freezer blast!

Lol... i read this as a "Taser" 

I wonder if you could use a Taser to kill the worms... ::)

Just leave the speargun at home and take out the taser...skip the spear step completely.  Big enough battery you could probably cook it too  ;D

If you candle them you’ll start seeing them. They look like a darker spot inside the meat. Once you cut down into the meat that far a big stringy worm will be exposed. Or you can just stay in denial and keep eating them like you have been.  !p

Well thanks everyone! This thread was like a crab pot, I came back and visited this morning and there's some great stuff here! I am excited to try candling the filets. What a great idea and my dad just gave my husband and I each 1400 Lumen NEBO Blast flashlights for Christmas so I am going to light up our ling filets tonight before BBQing. 2800 Lumens - maybe that will even cook the fish right there!!

Sorry to keep up the grossness, but the biology of it all is just amazing and brings up interesting thoughts.

I wonder from the point of view of the Cabezon what life is like with those worms. Really, if I had a giant worm scooting around my muscle tissue, I'd like to think I would be aware of it, and probably in some kind of pain, but maybe the worm has evolved to operate in a way that allows fish to be maximally effective at staying alive and relatively healthy (and therefore creating the best possible home for the worm).

Do you think that really big fish would be found with worms as frequently as smaller fish? Or is it only smaller fish (ie the worms kill or contribute to the death of the fish before they can get really big and old).

I'll share the results of the filet candling later, if it's anything interesting.

Your success and life as a parasite suffers if you do too much harm to your host. I doubt that fish are bothered by anasakids but what fish might feel is very well beyond my comprehension.

Parasites have many types relationships with their hosts. The fish may be an intermediate host for the parasitic larvae. The larvae may develop into another stage when ingested by a seal where it may reproduce and re-enter the food chain back to the fish. In this case the parasite could cause infection or death in the fish and not interrupt its own life cycle.

Don’t assume that parasitic relationships aren’t harmful, many parasites eventually kill their host.

Yes, true. I was being too general there. It would appear though that anasakids don't harm fish too much but again, I could be mistaken.

I wish I didn’t read this post before consuming the cabs from Friday and Saturday. Sure enough there were worms before cooking and while eating my taste buds were paranoid. Gotta get used to it. I couldn’t  mention it to my wife though as she was enjoying it.

My friend Nate has a video clip. He cooked his fish, apparently lightly, and had it on the plate. Him and his girls are going after it with chopsticks. Then in the middle of the fish a worm crawls up and started squiggling around. lol see if I can find the clip.

We candled the filets. Honestly I was a little disappointed after all this to find them beautiful and worm-free. And the lighting was very dramatic, especially the scatter illuminating the entire filet, and the second picture with beams of light literally emanating from the fish. Next time I will experiment with leaving skin on one side and seeing what the ling pattern looks like lit from underneath. I bet a blue filet illuminated this way is spectacular!! Enjoy!

Have you guys seen cymathoa exigua yet? They're fun. I've found quite a few from fish from the south jetty and am quite dissapointed as I haven't found any since. (There were some really large ones I had come crawling out of a ling or two... like the size of two nickel... or quarters even... *get's bigger every time I remember it*. The fun thing about them is they like to stick to your dive gloves when you're already freaked out and then you look like a girl when you're squealing and trying to shake them off.

Also .. not parasitic per se, but does anyone know about these little weird things I get on my wet suit when I brush up against some hairy rocks in the deep dark murky waters of the north jetty? I'll get them covering one of my arms and they look like the letter "J" and they sort of flop around and wriggle aggressively all the while being completely secured to your wetsuit.

(On a different note) I have a quick vid of a copper I'll get it uploaded for you all. (tons of them in Humboldt bay... especially at night).

Are you sure those hairy things you're brushing against are rocks?

(sorry, other than that I have nothing useful to add to the discussion)

(and thanks for plugging a new thing into my brain that I now have to watch out for)

Really interested in that one. The tiny brown saltwater leech thingies.

Are they pile worms?
