Research published today by the Food Standards Agency shows that a significant proportion (76%) of oysters tested from UK oyster growing beds contained norovirus. The virus was detected at low levels in more than half of the positive samples (52%).
It is difficult to assess the potential health impact of these findings, as the available research techniques are not able to differentiate between infectious and non-infectious norovirus material within the oysters. Furthermore, a safe limit for norovirus has not been established.
