Posibles problemas derivados del
contenido en mercurio del pescado
Basado en una nota del EWG y en un comunicado del FDA

a Agencia Alimentaria de Estados Unidos (FDA), ha anunciado que próximamente revisará sus recomendaciones respecto al contenido en mercurio de ciertos pescados, especialmente en relación con sus posibles efectos sobre mujeres embarazadas.

La FDA recomendaba hasta ahora que las mujeres embarazadas se abstuvieran de consumir las especies con mas probabilidades de tener un alto contenido en metil-mercurio, entre las que están el pez espada, el emperador y la caballa, mencionando que se pueden consumir con seguridad 12 onzas (340 gramos) por semana de pescado de otras especies distintas de las mencionadas.

Un reciente informe del grupo Environmental Working Group (EWG), ha puesto en tela de juicio las recomendaciones de la FDA, que cree insuficientes en relación con el peligro que entiende que supone la contaminación por mercurio para el feto, motivando que la FDA haya decidido convocar para revisar la información disponible. Concretamente el EWG pide criterios mas estrictos en las recomendaciones y que se incluya el atún, tanto fresco como enlatado, entre los alimentos peligrosos para el feto.

FDA ANNOUNCES FOODS ADVISORY COMMITTEE TO MEET ON METHYL MERCURY IN SEAFOOD

The Food and Drug Administration (FDA) today announced that it will soon schedule a meeting of its Foods Advisory Committee to review issues surrounding methyl mercury in commercial seafood. This review will include a re-examination of FDA's most recent Consumer Advisory, issued in January 2001 and revised in March 2001, for pregnant women and women of child-bearing age who may become pregnant.

The advisory recommended that these women should avoid eating the four fish species with the highest levels of methyl mercury: shark, swordfish, king mackerel, and tile fish. It concluded that these women could safely eat 12 ounces per week of a variety of other fish, with the emphasis on choosing a variety of different species.

At that time, FDA set forth its rationale for this decision in a formal, publicly available document, "Rationale for Issuance of Revised Advisory on Methyl Mercury and Fish Consumption." This document is available on FDA's web site at http://www.cfsan.fda.gov/~acrobat/hgadv4.pdf.

A recent report by the Environmental Working Group calls into question the basis for FDA's Consumer Advisory and the way in which FDA reached its conclusions on methyl mercury in seafood for this group of women.

FDA stands behind the process that led to its current Consumer Advisory on this subject, as well as the science that supports that advisory. In reaching its conclusions about methyl mercury in fish, FDA met with a broad range of interested parties, including consumer groups, health professionals, industry, and state public health officials.

Nevertheless, as a science-based agency committed to openness and transparency in its processes, FDA is convening its Foods Advisory Committee to meet in an open, public forum to discuss this important public health issue.

FDA expects to hold the meeting on methyl mercury in seafood later this spring. Details concerning the time and place of the meeting will be published in the Federal Register.

El pescado azul, y concretamente las especies mencionadas, se considera por una parte un alimento saludable por su alto contenido en diversos elementos de gran valor nutritivo como ácidos grasos esenciales, Omega-3 etc.

Sin embargo existen, por otro lado estas dudas sobre los efectos de su posible contenido en mercurio. De existir este problema en EEUU, en España existiría también y en mucha mayor medida, ya que los peces son los mismos y el consumo per capita de pescado total y de pescado de estas especies es en España mucho mas elevado que en EEUU.
