Are fish with worms ok to eat?

I've been meaning to ask this since I got back from the boundary waters last month.  We mostly saw it in perch, but once we noticed it and started looking we saw small worms inside the mouths of practically every fish we caught and when I filletted fish for lunch saw them embedded in the fillets.  Has anyone else ever seen or heard of this?  I would assume they would die after a bath in hot grease, but I don't know.

    As long as you cook the fish well enough to kill the worms and can get past the Yuk factor they are safe to eat.

    Cooking kills the worms, but I wouldn't eat them if the meat is riddled with them...Since you would be eatting more worm than fish ...

    I wouldn't even have considered it, but once we finally started looking for them we noticed them in just about every fish we caught.  And we caught hundreds of fish.  Everything... crappies, perch, smallmouth, largemouth, walleye and pike all had some in them.  I mainly noticed them in the meat of the perch, but a couple of the walleye had them embedded in the meat.  The way I figure it, if it was something really bad, we would have heard about it from someone along the way because that place was PACKED.  I'm sure other people noticed it.  2 dog, you might be right on the leaches.  The fish that had them in the roof of their mouthes could have definitely been small leaches.  I actually made a comment to that affect to my buddy when I first noticed it.

    Yeah, I wouldn't go there. Me and my bro went to some ponds in Butler Co. and caught a mess of huge bluegills only to find out later that the fillets were filled with worms.

    I did a little research on the internet and it seems most of the fish we catch have them.  It seems to suggest that they are tapeworms, but normal cooking to 140 degrees will eliminate the problems.  Odds are, we've all eaten them.

    Here's the sites I checked out if you wanna look as well.

    Yeah, I bet we have all eaten a worm or two in our days.  But if I actually seen them in the fillets there is no way I'd be eating them.

    Black spot disease is commonly observed in rock bass and other sunfish, bass, pike, perch, minnows, and other fish species. It can be identified by the presence of small black spots, usually about the size of a pin head, in the skin, the fins, the musculature, and the mouth of the fish. The black spots are caused by pigment that the fish deposits around the larval stage of a parasitic digenetic trematode, usually a Neascus spp.
    The lifecycle of the "black spot" parasite is complex. The adult parasite is found in a fish eating bird, the kingfisher. The larval parasite is transferred from the infected fish to the bird during the feeding process. In the kingfisher, the larval stage develops into an adult parasite. The adult parasite in the intestine of the bird produces eggs that are eventually deposited in the water. There the eggs mature, hatch, and develop into the miracidium stage of the parasite. The miracidium infects a snail. In the snail, the miracidium develops into the cercaria life stage. The cercaria leaves the snail and actively penetrates a host fish. In the fish, the parasite becomes encysted. In about 22 days, black spots form around the cyst. This entire lifecycle takes at least 112 days to complete.
    In general, the presence of the "black spot" parasite does not affect the growth or the longevity of the infected fish; however massive infections in young fish may cause fish mortality. The parasite is incapable of infecting humans and, as is the case with all fish parasites, it is destroyed by thorough cooking. When fish are heavily infected, some anglers prefer to remove the skin to improve the appearance of the cooked fish.

    Tape worms can lead to a vit. B12 deficiency.  If not caught and treated, it can be fatal, or have irreversible nerve damage.  Not something you want to mess around with.  I recently had blood work done, with low levels of B12.  I'm guessing it was more diet than anything though.  I will no longer eat sushi, and even fried fish is suspect.  I would throw back any fish with visible worms in their mouth, and likely stop fishing the water.  It only takes one egg to get into your system, to infect you.

    The way I figure it, if it was something really bad, we would have heard about it from someone along the way because that place was PACKED.  I'm sure other people noticed it. 



    Very good reasoning! Jeezsh!

    If you cook the fish properly, you'll kill the larvae, but you're still eatin' worms brutha. A lot of fish during the summer are riddled with them. Little yellow spots in the fillets are the worms. There's usually too many(100's)to pick them all out, so if you're gonna eat the worm meat, cook it well.......

    Yep, EVERY lake I have fished in PA and that I pulled panfish from has had, at one time or another, the yellow parasites in them.  Wilhelm and Pymy always had them later in summer.  Glendale and many of the smaller lakes in Cambria County have them.  You won't be eating much panfish in PA if you won't eat the worms.  If you look hard enough, especially later in summer, you'll find em.  Thoroughly cook em and don't eat sushi from freshwater fish and you'll be fine. 
     
    Yellow Grub (From the PFBC website)
     
    Yellow grub
    Your description suggests you observed encysted metacercariae larval stage of the yellow grub (Clinostomum) parasite. The encysted, yellow to yellowish white worm can be up to 1/4 inch in length. It can be found in virtually all species of North American freshwater fish.
    The yellow grub is a digenetic trematode. These types of parasites require several hosts to complete their life cycles. In the case of the yellow grub, the adult parasite is found in the throats of fish eating birds, such as herons. During the feeding process, eggs produced by the adults are washed out of the bird's mouth and into the water. There they hatch, yielding a free swimming larval stage (miracidia) that will die within several hours if it does not find and infect a snail of the genus Helisoma. After further development within the snail, a free swimming cercaria leaves the snail and seeks a fish host. The cercariae burrow through the skin of the fish and encyst, where they develop into the metacercariae. These yellow grubs may live several years in the fish. If the fish is eaten by the bird host the larval metacercariae will develop into adult parasites, completing the life cycle.
    Infestations by a few individuals likely cause little harm to fish, however, under certain circumstances, heavy infestations can kill fish. Yellow grubs are described as unsightly by fishermen. A related species occurring in Asia has been found to infect the upper respiratory tract of humans. Thorough cooking kills the North American yellow grub and the parasite does not alter the flavor or the infected fish; however, fish with heavy infestations are typically not eaten by anglers.
    Infestation is somewhat greater for fish caught in shallow water where snails and fish eating birds are most prevalent. Fish caught from deep water typically exhibit less infestation. Like many biological phenomenon, prevalence of the grub may be greater in some years and less in others for a variety of reasons including an abundance of intermediate host mollusks and birds.

    Yep, not sure what he found in their mouths. But the black spots on the filletes, and sides of them are parasites, at least they are black spots in winter early spring, I don't keep many fish locally in summer, fishing for big fish then.  But if you've eaten 20 panfish from PA waters, then you've eaten these parasites.  No problem if cooked, you won't/didn't even know. That said, If I notice a fish is extremely infected when caught or when filleting, it get's tossed. Most I've noticed was from Lake Latonka Bluegills when I got the chance to fish there, the crappies and perch weren't as effected there, but the Bluegill during spring were pretty bad. I've seen them everywhere, including presque Isle bluegill and all the local lakes. Seem to be more abundant in spring/summer than winter.

    I think the ones that I saw in the meat was the "yellow grub" from up above.  The fish that we caught with them were all in shallow, 75 degree water.  The ones with the stuff in the roof of their mouths may have been leaches.  I don't know.  I'm not worried, but some of the rest of the group were.  90% of my diet is pasta, deer, and fish.  I'm sure I've eaten worse.  If a little worm makes it through the boiling oil and kills me, then it was just my time I guess.  Thanks for all of the input guys.  We can put this thread to rest.

    It may be of additional benefit to freeze the fish for a few weeks to kill parasites efore cooking them as an added safeguard.  Bet they are definatly better fresh.  If the fish commision has put out a warning iw ould say its safe.  just cook the sh*it out of them.

    Seriously, if you got a beef steak or pork chop that had worms in it would you ask yourself the same question?
     
    If you even ask yourself the question of "do i eat this" in that case there is something wrong with you.
     
    Go to some cleaner water or if you are going to continue fishing in that spot fish for the sport and go to wholeys or benkovitz for your eatin' fish.

    I remember about 35 years ago eating some worms out of the bottles of tequila, and looks like i survived. My suggestion is cook them fillets in tequila!

    There's worms in pork too. 

    Here's the proof!

    I don't think any food is that good to eat that I could get past the sight of the worms in it to eat it. Sounds like something they would have on Fear Factor.

    Just one more reason for me to NEVER eat a fish. Monsters inside me perch?

    I would never intentionally eat parasites.....cooked to 140/180/2000...NO WAY!


    P.S. We cleaned alot of perch this year...I did'nt notice any "worms"
