Just in time for Lent-which starts Feb. 6-Oceana, a Washington-based conservation group, has issued a new report called “Hold the Mercury: How to Avoid Mercury When Buying Fish.” The group notes in its news release that the food of choice for practicing Catholics on Lenten Fridays could have mercury levels that pose health risks. So, they suggest holding the tuna. “If seafood is on the Lent menu, wild salmon or tilapia might be a safer choice so women and kids can get the nutritional benefits of fish without the risks,” recommends Jacqueline Savitz, Oceana’s senior campaign director.
