Toxin Talk

Some would have you believe that fish consumption is all beneficial

Toxins in Striped BassYesterday morning, I happened to be talking with another avid recreational fisherman about the presence of toxic elements and chemicals in some of the fish that anglers like to catch and a lot of people like to eat. The discussion centered on striped bass and the health warning posted in just about every Atlantic coastal state, with the exception of Massachusetts, where migratory striped bass and bluefish are caught.

Then, out of the blue, comes an email press release that the Food & Drug Administration is being sued because it has failed to respond to a petition filed in 2011 that requested (1) informational labeling on packaged seafood that reflects the joint recommendations of the FDA and the Environmental Protection Agency in their online advisory; (2) consumption recommendations at the point of sale of unpackaged, fresh seafood, presented in a user friendly format; and (3) informational mercury level and consumption limit labeling on packaging or at the point of sale for seafood species with moderate or high mercury content that are not otherwise listed in the online advisory. http://www.fda.gov/Food/FoodborneIllnessContaminants/BuyStoreServeSafeFood/ucm110591.htm

Bingo! So the two of us having the discussion are not the only ones wondering why there is not more public awareness of this problem and why there are not more comprehensive requirements for making the public aware.

In my case, it is probably too late to worry about this problem. But I have four grandchildren, and they are likely to be impacted by their consumption of some fish. My children should be given the information that will allow them to make the right decisions for their children. Studies have shown that methylmercury, which occurs when airborne mercury is saturated in water, is a neurotoxin that leads to learning disabilities, lowered IQ, and impaired cognitive and nervous system functioning. Studies also have shown that PCBs have a known neuropsychological effect in children and can cause an elevated risk of cancer. Both of these contaminants bio-accumulate, primarily in fatty tissue. A copy of the study can be found at http://www.maine.gov/dhhs/mecdc/environmental-health/eohp/fish/documents/9-08final.pdf.

So, here we have a fairly comprehensive study of contaminants in fish and the potential hazards to the sensitive group, which consists of women of child-bearing age as well as young women and children. That group is advised by this study to consume from one meal a month to zero consumption. Others are advised to consume no more than one meal a month – not exactly an endorsement for eating seafood.

Virtually every state from the Mid-Atlantic to Maine has posted these warnings except for the state of Massachusetts. Why, I cannot find out. It may have to do as much with the workings of state bureaucracy as any other possibility. Some think that this has been done to protect the commercial striped bass fishery. I don’t know, but I do know is that it is not protecting the general public. There may be some reasoning by state health officials that they do not post the health warning. That has to do with the testing methodology. Methylmercury bio-accumulates in the fatty tissue. In some testing methods the entire fish is ground up, and the testing is done on that. This gives a lower reading of the toxic contaminants than if the test had been done solely on the part of the fish normally consumed.

It still seems strange to me that almost all the coastal Atlantic states have some level of warning about consumption of bluefish and striped bass. Most of the states in the Atlantic States Marine Fisheries Commission took part in the study workgroup, in which Massachusetts had three participants. All of the New England states except Massachusetts since have posted health warnings about consumption of these fish. It seems odd to me that when fish cross the imaginary state line into Massachusetts waters they somehow become cleansed. Could be, ya know! There have been other Massachusetts Miracles. And if you believe that…!

    The biggest argument for bag limits of 2 striped bass a day is so fishermen can “keep a few for the table”. However, they should only be eating one striped bass meal a month at most…

    Shows that the state only really cares about bringing in money. And the commercial and tourist striper fishing brings in billions to the state.
