MedicalResearch.com Interview with: “Fish” by Dhruvaraj S is licensed under CC BY 2.0Dr Caroline M Taylor Wellcome Trust Research Fellow Centre for Child and Adolescent Health Bristol Medical School, University of Bristol Oakfield House, Oakfield Grove, Bristol MedicalResearch.com: What is the background for this study? Response: Mercury is a toxic metal that is widespread in the environment. In pregnancy, mercury in the mother’ bloodstream is transferred through the placenta to the fetus, where is can affect development of the nervous system. Mercury from vaccines has been the focus of attention particularly in regard to a link with autism in children. However, the amount of mercury used in the vaccines is small in comparison with mercury from the diet and atmospheric pollution, and in the EU at least, childhood vaccines no longer contain this preservative. The fear that mercury is linked to autism has persisted, despite increasing evidence that this is not the case. The aim of our study was to look at mercury from the diet rather than vaccines – specifically from fish – in pregnant women. We measured the women’s mercury levels in their blood and asked them about how much fish they ate. We then followed up their children for 9 years and recorded how many of them had autism diagnosed within that time. We also measured how many of them had autist traits by measuring their social and communication difficulties.  The data were part of the Children of the 90s study (Avon Longitudinal Study of Parents and Children – ALSPAC), which is based in Bristol, UK.

Prof. Peter B. Marko Department of Biology University of Hawaii at Mānoa, Honolulu, HawaiiMedicalResearch.com Interview with: Prof. Peter B. Marko Department of Biology University of Hawaii at Mānoa, Honolulu, Hawaii Medical Research: What are the main findings of the study Prof. Marko: The main finding of the study was that species substitutions and fishery stock substitutions together obscure a complex pattern of mercury contamination in Chilean sea bass (or Patagonian toothfish) that can put consumers unknowingly at risk of ingesting greater levels of mercury than the labeling would suggest.  Although it is well appreciated that mercury levels vary dramatically among different species of fish, and that species substitutions have the potential to expose consumers to unwanted mercury, our study shows that for Chilean sea bass, fish mislabeled as to their country or region of origin (but labeled as the correct species) have a high potential to expose consumers to unexpectedly high levels of mercury.
