Seafood is usually avoided not because it is poisonous, but
mainly because the risk of internal infection from eating it after
an op is higher than other consumables.
Especially if you are taking antibiotics after an op involving your
kidneys, liver or intestines. (Digestive system related)
The doctor should be able to properly advise you on what to avoid
and what to eat. For one, i can recommend you take more liver in
your diet.
