Assessments of SCI 1 and SCI 2 stocks have been updated, and both were accepted. For SCI 1, SSB remains stable at around 75% SSB0. Fishing intensity has consistently been below F 40% B0. For SCI 2, SSB has decreased recently, but remains between 73% and 78% SSB0. Fishing intensity peaked in 2002 but has declined in recent years, while SSB/SSB0 has increased.
NZFS commissioned a project to inform risk models by providing estimates on expected bacterial growth for different scenarios of
chiller failure. This was to facilitate faster decisions around acceptance/rejection criteria for raw milk, and so limit the quantity of
milk discarded. The outcome of this work is guidance on the potential micro-organism growth during chiller failure, enabling a
robust estimate on if milk is not fit for purpose.
Extended shelf-life milk, when produced by thermal processing, applies parameters between those used for traditional pasteurisation and ultra-high-temperature sterilisation. The goal of this study was to identify the food safety issues that must be considered. Of particular concern is the presence of spore-forming organisms. This review supports the current approach of considering production on a case-by-case basis, and requiring validation studies to assess the bactericidal effect of a process.
This report describes developments towards an assessment model for low information stocks using spatially explicit catch, abundance and harvest rate estimates. Generalized Additive Models (GAMs), applied to research trawl survey data and environmental covariates, provided spatial extent and relative spatial density for seven stocks, chosen to include a range of information states. Methods investigated included a spatially explicit risk assessment model and a catch only method
