BOSTON (AP) -- State public health officials are warning lobster lovers to avoid the soft green substance found in the body cavity of lobsters.
  
The tomalley is considered a delicacy by some seafood aficionados, but the state Department of Public Health says this part of the lobster can build up high levels of toxins and pollutants.
  
That's of particular concern this year because of red tide, a toxic algae that closed shellfish beds along large swathes of New England's coast earlier this summer. Eating shellfish with high levels of the toxin can cause potentially fatal paralytic shellfish poisoning.
  
The tomalley can also accumulate high levels of possibly carcinogenic PCBs.
  
Health officials say the regular lobster meat is safe.
