 No Limit*   : Although there is currently no health concern for this fish, there is not sufficient data to designate it a KidSafe Seafood at this time.  As a general rule of thumb, the EPA and FDA recommend that young children eat up to two average meals a week of a variety of low-mercury fish and shellfish.
