RESuLTS Live Shellstock Irradiated Oysters 0 Doses of 0.5 and 1.0 KGy showed signScant 5 log reduction in levels of V: vulni~cW (4.6 x 16 to 4.6 and 2.3 MPN/g respectively) without causing si,onificant increases in mortality as compared to the controls through 14 days post harvest (shelf life for live oysters). Fresh Shucked Irradiated Oysters 0 There were no detectable levels of i? vuZnzj?cu.s in irradiated fresh shucked oysters, even at the lowest dose of 1.0 KGy. 0 Even non-irradiated controls dropped from 4.6 x lo6 to < 5 MpN/g by 14 days post harvest on ice in cold storage at 409; by 17 days at 409, there were no detectable V mlni$cm in non-irradiated controls. Ef&‘-Shell Frozen Irradiated Oysters 0 There were no detectable levels of V. vuZnz~cus in any of the irradiation-processed frozen half-shell oysters, even at the lowest dose of 1.0 KGy; non-irradiated controls dropped to
