Ciguatera

 I named this post  that so if anybody were to Google that and then find this blog and it helps them I would be very gratified. If even one person finds this and because of it avoids the horrible health effects that I've had I would feel wonderful...AND, it wasn't really my idea. Years ago when I first began to think I might be suffering from this fish toxin I googled and found a blog of a Fishing Guide in Australia who's age, work and lifestyle mirrored mine and he suffered terribly form Ciguterra for years . So here goes .

That Robalo there is about the finest eating you fish you can catch here in Mazatlan. I caught that fish right there at low tide about 2:00 pm Sunday and filleted it and cleaned it immediately taking special care to get ALL the red and blood out of the fillet. MP fried it in batter as usual and because I had not eaten ANY fish from the waters of Mazatlan in 3 years because I suspected I had the Ciguterra Toxin in my system I ate only I/4 of a fillet....and oh boy was it ever good .  I slept well, got up and had my coffee and read my papers and was on the beach at 6:00 am to fish . I wandered and fished my way down to El Cid and visited with my friends a bit and then decided to fish the rocks on the other side of our building . As I got back right in front of my building I felt kinda weird, kinda light headed and then the next thing I knew I had falling forward and couldn't catch myself from falling down . Then I fell several times trying to stand but finally got upright and floundered up to the foot shower of my building. Even as I sat there I couldn't keep my balance, I thought I was having a stroke was petrified. I called MP and she came running and as I recovered she and Alan our maintenance guy held onto to me to our condo unit. I immediately had to go to the bathroom and had severe diarrhea. Within two hours I could walk without help. Now 3 days later I'm just a bit unsteady but still having G.I. issues.

Ciguterra is the most common of a few Fish Toxins, 50,000 cases a year of which 15,000 are in the USA.  There is no test for it and diagnosis is made by the process of elimination.  It occurs between the two tropics, Cancer and Capricorn at 35 degrees north and 35 degrees south Latitude. Small fish eat the coral and big fish eat the small fish and we eat the big fish. The fish most apt to carry the toxin are in shore predator fish like Barracuda, Snappers , Grouper and Sea Bass which are much akin to that Robalo ( snook ) . The Toxin accumulates in the human system being stored in your fat cells. It is rarely fatal and effects different people in different ways. The amount of toxin in your system depends on your exposure  to fish, so people like me who catch, handle and eat fish as a lifestyle can be most affected. Some people it doesn't effect at all. 

The top pic is a Corvina which is Sea Bass. The middle pic is a nice big Pargo, red Snapper and the 3rd pic is our fishing team with a load of Corvina, some really nice big ones...the bigger the fish the more toxin.

As the years went on we realized that often after eating fish I would get sick, usually vomiting the fish up during the night. Many a time we had fish with other couples and I'd be the only one sick. Many nights after dining I would just feel queasy. Years ago a renowned fisherman warned me of the Ciguatera. He told me I was the perfect person to become infected with the toxin. I eat it at least once a week and through the years of I've handled hundreds of these fish and thousands of fish in general. An interesting thing is that once you have the toxin in your system the fish that makes you sick usually won't have the toxin but any fish you might eat can trick your system into releasing the stored toxin into your bloodstream .

Ciguatoxins are lipid-soluble and can be stored in the body's tissues, including fat, for a long time (months or even years). The symptoms experienced by individuals who "carry" the toxin (meaning they have residual toxin from a previous exposure) can recur intermittently, especially when triggered by certain factors like consuming alcohol, nuts/nut oils, or even more fish. 

Gastrointestinal symptoms
  • Nausea
  • Vomiting
  • Diarrhea
  • Abdominal pain or cramps 
Neurological and sensory symptoms 
  • Tingling or numbness around the mouth, lips, and throat, spreading to hands and feet
  • Sore muscles
  • Tooth pain
  • Temperature reversal: A sensation where hot objects feel cold and cold objects feel hot. This is considered a hallmark symptom.
  • Itching, which can be extreme and worsened by alcohol
  • Headaches
  • Dizziness
  • Fatigue or weakness
  • Difficulty walking
  • In severe cases, hallucinations or coma 
Important considerations
  • Symptoms usually appear within minutes to 24 hours after eating the contaminated fish.
  • Most people recover fully within days or weeks, but some neurological symptoms can persist for months or even years in rare cases.
  • There is no antidote, and treatment is supportive, focusing on managing the specific symptoms. It is recommended to seek medical attention for diagnosis and treatment.
  • Avoid alcohol and vigorous exercise, as these can worsen the symptoms.
  • To prevent recurrence, some medical professionals advise avoiding fish, nuts, and alcohol for up to six months after recovery. 
  • So now I'm having neurological problems that you see in the info. I have a friend here who knows Mazatlan and is a true waterman. He swears that my condition can't be ciguatera because he's never seem coral around Mazatlan...Well, it's obvious now that he's wrong. I think the fact that fish have fins to take them wherever they'd like might have something to do with the riddle of no coral....
  • The internet is a wonderful thing. If you or somebody you know seems to get food poisoning a lot and fishes the tropics....look into and try to head it off before you get to the point that I have. But ya know me, Mr Bright side, if I had been anywhere else than the beach and fell that hard I could of been really hurt.....so....no pescador zarenado, no pescador entero, no pescador diablo....I'm done with that !
