I haven't eaten crabs for a long time because I am afraid of mercury poisoning...
AI Overview
While crab consumption is generally considered safe, it's important to be aware of potential mercury contamination, particularly in certain types of crabs and locations. Mercury levels can vary, and some crabs, especially those found in specific regions or with higher mercury levels in their diet, may pose a higher risk.
Here's a more detailed look:
- Mercury in Crabs:
Crabs, like other seafood, can accumulate mercury from their environment. Mercury exists in different forms, with methylmercury being the most toxic and readily absorbed by the body.
- Species and Location: Some crab species, like brown crab, may have higher mercury levels than others. Crabs from areas with higher mercury contamination in their environment will also tend to have higher levels.
- Size and Age: Larger, older crabs may accumulate more mercury over time.
- Diet: Crabs that consume other contaminated organisms, especially bottom-dwelling species, may have higher mercury levels, according to a study on ScienceDirect.com.
- Potential Health Risks:
Exposure to high levels of mercury, particularly methylmercury, can have toxic effects on the nervous system, kidneys, and other organs. Pregnant women and young children are particularly vulnerable to mercury's harmful effects.
