So as my wife and I were doing some research in hopes of promoting a solid diet and healthier lifestyle (and because she is pregnant right now), here is the list of those saltwater fish species that could do more harm than good to you and your health if eaten out of moderation. Strong Angler Cameron Parsons with a nice king fish FDA warns children, pregnant women and lactating moms to NOT eat any king mackerel due to their very high mercury content.
Eliminating these fish species in your diet can definitely reduce your chances of getting exposed to the harmful effects of mercury and other existing contaminants. Whether fresh or canned, Albacore still has mercury levels that are almost three times higher than the smaller skip jack.
According to a CNN report, this type of fish has extremely high levels of metal mercury that can eventually cause coordination loss, blindness and even death, depending on the amount or portion ingested. Scientists believed that such increased mercury content was due to the accumulation of certain contaminants in their body as they eat lots of smaller fish.
“What we found for our 124 sharks that we sampled was that about one-third of them came in with mercury levels that were over the Food and Drug Administration’s action level of one part per million,” Robert Hunter, director of Mote Marine Laboratory’s Center for Shark Research in Sarasota, said in a statement. The cobra is a delicious saltwater fish that sadly can soak up a lot of mercury.
Strong Angler Tina Corrode with what’s left of her swordfish you like catching daytime or nighttime swordfish, you might want to be careful how much of it you eat. Because swordfish is up at the very top of the list in terms of mercury content for saltwater fish.
Although most people throw back jacks and refer to them as a “junk fish ”, but for those of you that do eat them, be careful! Greater Amber jack South Atlantic grouper (i.e. gag, scamp, red and snowy) Tile fish (also called golden or white snapper) Banded Rudder fish.
One thing that most of the articles failed to mention was the role that selenium plays in fish. Needless to say, it’s basically what you know (i.e. lowering your mercury risk exposure) that can really help you keep a healthy mind and body.
NOTE: On February 8, 2006, technical changes were made to the data that was posted on January 19, 2006. The changes corrected data or more properly characterized the species of fish or shellfish sampled.
On October 6, 2014, technical changes were made to allow viewers to review the list in order of mercury levels and in alphabetical order by fish species. It’s released into the environment in several ways, including through industrial processes like burning coal or natural events like eruptions.
People can be exposed to this toxin in a number of ways, such as breathing in mercury vapors during mining and industrial work. You can also be exposed by eating fish and shellfish because these animals absorb low concentrations of mercury due to water pollution.
The amount of mercury in fish and other seafood depends on the species and the levels of pollution in its environment. One study from 1998 to 2005 found that 27% of fish from 291 streams around the United States contained more than the recommended limit (2).
These include shark, swordfish, fresh tuna, marlin, king mackerel, tile fish from the Gulf of Mexico, and northern pike (5). Eating fish and shellfish is a major source of mercury exposure in humans and animals.
One animal study revealed that exposure to even low doses of methyl mercury during the first 10 days of conception impaired brain function in adult mice (26). Another study indicated that children exposed to mercury while in the womb struggled with attention, memory, language, and motor function (27, 28).
Following these tips will help you maximize the benefits of eating fish while minimizing your risks of mercury exposure. US government scientists tested fish in 291 streams around the country for mercury contamination.
The U.S. FDA recommends eating 8 – 12 ounces of fish low in mercury per week. Fish contain vital nutrients including omega 3 fatty acids, protein, vitamins, and minerals such as iron.
These nutrients are essential, particularly for pregnant moms, as they foster healthy fetal, infant, and childhood development. Mercury is defined as a chemical element with symbol Hg and atomic number 80.
Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure.
That is why larger, longer-living predators such as sharks and swordfish tend to have more of the toxin than smaller fish such as sardines, sole, and trout. US government scientists tested fish in 291 streams around the country for mercury contamination.
The presence of mercury in fish can be a particular health concern for women who are or may become pregnant, nursing mothers, and young children. Mercury levels in the Northern Pacific Ocean have risen about 30 percent over the past 20 years and are expected to rise by 50 percent more by 2050 as industrial mercury emissions increase, according to a 2009 study led by researchers at the U.S. Geological Survey and Harvard University.
Materials presented are in no way meant to be a substitute for professional medical care by a qualified practitioner, nor should they be construed as such. Abstract: List of low and high mercury concentration levels in fish species, includes chart of fish species safe and not safe for pregnant women and public consumption.
For that reason, women who are planning to become pregnant may want to begin to avoid fish that are higher in mercury before they become pregnant. The effects of methyl mercury poisoning include cerebral palsy, blindness, deafness, impaired mental functioning, impaired lung function, growth problems, and having a small head.
