Hi, I was a scuba instructor until 4 weeks ago when i got the positive result. (8 Wks preg now) As you can imagine freshly caught seafood was part of the diet, now however it is restricted. All shell food holds a risk anyway, so i have chosen to not take any.Did you know that certain times of year we could not eat the scallops? As for tuna.. i heard from the family planning clinic that should be on the do not eat list too now..(high mercury levels).. Most of the smoked and cooked fish you buy from the fishmonger is fine and even healthy for us. hope this helps.
