Yes, but it's probably minimal in modern pewter. In 17th or 18th century France it was noted to cause some rather nasty symptom which were reprised in the 'Dorset Dropsy' of later times. 'Dorset Dropsy' was found noted to occur in cider drinkers but couldn't, initially, be linked to lead poisoning as cider, in England, was being drunk from earthenware vessels. Eventually they found that lead solder was being used to repair the oaken boards that the fruit was chopped up on!
