FYI - Grouper

Just received this email - I thought it was the adult beverages the whole time :lol:

Warning from the Bay County Health Department:

The Food and Waterborne Disease Program received some information from FDA -Florida District of 5 ciguatera illnesses from consumption of grouper (state of residence unknown at this time - original information came from the FDA Baltimore District). The trace back implicated a firm in the Panama City, FL area. The firm has been contacted and has reported that over half of the lot of grouper implicated in the illnesses was distributed in the local Panama City area.

Ciguatera Fish Poisoning is a form of human poisoning caused by the consumption of subtropical and tropical marine finfish which have accumulated naturally occurring toxins through their diet. The toxins are known to originate from several <http://www.cfsan.fda.gov/cgi-bin/bbbglos?Dinoflagellida> dinoflagellate (algae) species that are common to ciguatera endemic regions in the lower latitudes.

Initial signs of poisoning occur within six hours after consumption of toxic fish and include perioral numbness and tingling (paresthesia), which may spread to the extremities, nausea, vomiting, and diarrhea. Neurological signs include intensified paresthesia, arthralgia, myalgia, headache, temperature sensory reversal and acute sensitivity to temperature extremes, vertigo, and muscular weakness to the point of prostration. Cardiovascular signs include arrhythmia, bradycardia or tachycardia, and reduced blood pressure. Ciguatera poisoning is usually self-limiting, and signs of poisoning often subside within several days from onset. However, in severe cases the neurological symptoms are known to persist from weeks to months. In a few isolated cases neurological symptoms have persisted for several years, and in other cases recovered patients have experienced recurrence of neurological symptoms months to years after recovery. Such relapses are most often associated with changes in dietary habits or with consumption of alcohol. There is a low incidence of death resulting from respiratory and cardiovascular failure.

Manifestations of ciguatera in humans usually involves a combination of gastrointestinal, neurological, and cardiovascular disorders. Symptoms defined within these general categories vary with the geographic origin of toxic fish.

Clinical testing procedures are not presently available for the diagnosis of ciguatera in humans. Diagnosis is based entirely on symptomology and recent dietary history. An enzyme immunoassay (EIA) designed to detect toxic fish in field situations is under evaluation by the Association of Official Analytical Chemists (AOAC) and may provide some measure of protection to the public in the future.

Marine finfish most commonly implicated in ciguatera fish poisoning include the groupers, <http://www.cfsan.fda.gov/~frf/rfe2gb.html> barracudas, snappers, jacks, mackerel, and triggerfish. Many other species of warm-water fishes harbor ciguatera toxins. The occurrence of toxic fish is sporadic, and not all fish of a given species or from a given locality will be toxic.

Looks like this is about all we can do, then? Looks like my cats have a new job :lol:

In Northern Australia, where ciguatera is a common problem, there are two commonly believed ways of determining that fish carry significant levels of ciguatoxin. The first belief is that if a piece of fish is contaminated with the toxin, flies will not land on it. The second belief is that the toxin can be detected by feeding a piece of fish to a cat as cats are allegedly highly sensitive to ciguatoxin and will display symptoms. It is not known whether there is any veracity to either belief. (From Wikipedia)

Until the warning is lifter, may I reccommend a recipe that RHTFISH posted for blues:
Put them on grill whole...begin drinking: consume 2 Makers Mark per
hour for 3 hours; open grill and feed whatever is left to the crabs or
buzzards; continue Makers Mark until you don't remember ever even
trying to grill the groupa!

Damn I love grillin dem groupas!

Grouper caught in the northern gulf do not carry ciguatera (or very small amounts). The most likely cause of the poisonings is other types of fish being passed off as grouper, or groupers caught in the Caribbean where it is prevalent. I would be much more worried about mercury than ciguatera.

Yeah, the "grouper" in question was sold in Panama City, not caught there. No problem with grouper in northern Gulf, but big cudas I still would not eat from anywhere. I'm not sure if they migrate from the south and wouldn't take the chance, although never heard of anything caught up here carrying cuguatera.
