Medical News Summary (summary of medical news story as reported by C News - Canada): Health Canada is following the lead of US authorities in reviewing the guidelines of fish consumption by women of childbearing age because of the risks posed by mercury. Research indicates that mercury can affect fetal brain development resulting in learning disabilities and lower intelligence. A US Environmental Protection Agency biochemist believes that roughly 1 in 6 pregnant women are placing their babies at risk because of high mercury levels. It is recommended that women eat no more than two meals of fish per week. Mercury can also cause high blood pressure in adults. Maternal blood should not exceed mercury levels of 5.8 micrograms per liter according to the US Environmental Protection Agency but Health Canada’s limit is 20 micrograms.
