Listeria monocytogenes is a foodborne pathogen often associated with ready-to-eat foods (RTE) where the food is consumed without any further cooking. Management and control of Listeria during food manufacture is therefore a particular focus of the food industry. All producers of RTE products are required to demonstrate compliance to limits specified in the Food Standards code. However, some RTE foods are difficult to sample. This project examines alternative sampling methods that can be used.

A survey of Foveaux Strait oysters (OYU 5) in February 2021 found all the key indicators show continued rebuilding of the fishery. Oyster spat settlement was high. Commercial-sized, recruit, pre-recruit oysters increased 28.3%, 51.2%, 83.6%, and 3.7% respectively since 2020. Increases may in part be due to inter survey variation. Bonamia was low in 2021 with prevalence of infection 5.4%, non-fatal infections 0.7%, and Bonamia mortality 4.3%, all similar to 2020, and likely to be low in 2022.
