The ban on shellfish harvesting during certain months of the year (which varies from state to state and on what type of shellfish) is generally to reduce over fishing and reduce disruption of the beds during the shellfish's reproductive phase, and has nothing to do with toxicity. Many shellfish are also less plump and flavorful during the reproductive phase. The increase in cases of food poisoning from shellfish is believed to be primarily due to increased pollution, as well as changes in salinity and rising water temperatures associated with increase rainwater runoff from developed areas. There are also a number of less well understood factors involved. :{ Rich in Va. http://www.erols.com/richstev Photo Trend Enterprises- A Restaurant Service Company > I've never had a problem w/raw oysters in all my years of eating > them - but > there are certain months in which they are not harvested (can't remember > which ones) something about toxicity or whatever - this may be what some > people are alluding to > > Sharen Rund Bloechl >
