Background
• NZFSA’s mission
– To protect consumers
– To enhance NZ’s position as a trusted supplier of food
• High rates of campylobacteriosis in NZ reflect an unacceptable health burden
• Raw poultry is considered to be a primary exposure pathway
• Risk management strategy required
![Page 3: NZ strategy for the reduction of foodborne campylobacteriosis Peter van der Logt, Science Group](https://reader035.vdocuments.net/reader035/viewer/2022070406/56649de35503460f94ada5a9/html5/thumbnails/3.jpg)
Objectives
• To reduce the incidence of foodborne human campylobacteriosis
• To improve knowledge of food attribution
• To understand the relative value of different interventions throughout the food chain in reducing risks to human health

Objectives (continued)
• To make informed risk management decisions on appropriate control measures and their implementation
• To design and implement an ongoing monitoring and review programme to assess the effectiveness of risk management decisions

Work streams of the strategy
• Development and implementation of
– Monitoring and surveillance activities
– Hazard based controls
– Risk based controls
• Communication
• International collaboration
• Other stakeholders

Monitoring throughout the food chain
• Caecal sampling of all cuts at slaughter, NMD information on farms
• Carcass rinses (2/day at large premises), NMD information on processing plants

Surveillance of foodborne illness
• Received report on Acute Gastrointestinal Illness (AGI) study from ESR
• Enhanced surveillance of potentially foodborne enteric diseases in NZ (Massey University and MidCentral Health, 2006-2008)
• Relative contribution of food pathways to the burden of human campylobacteriosis (NZFSA funded Massey University PhD student 2005-2009)
• Commissioned MLST geographic comparison study

Hazard based controls
• Draft report on transfer rates received from ESR
• On-farm survey (ESR) results expected soon
• Domestic freezing (ESR)
– Received report on temperature profiles
– Received preliminary results of domestic freezing experiment
– Planning more experiments

Hazard based controls
• Various decontamination trials carried out by industry
• Leak proof packaging
• Hazard based control paper in preparation
– Identifies options (and limitations) for controls
– ‘Living document’

Risk based controls
• Campylobacter in poultry model by ESR
• Successful, with Ministry for the Environment, in acquiring grant from Cross Departmental Research Pool
– To evaluate the role of the environment and relative contribution of various foods
– Collaboration between NIWA, ESR, EpiCentre, MfE and NZFSA

International Collaboration (Codex)
• New Zealand and Sweden leading the development of a new international Code of Hygienic Practice for Salmonella and Campylobacter in Young Chickens (Broilers) and Chicken Meat.
• About 30 countries and international organisations have volunteered to be part of the working group
• First meeting June 2007 in Uppsala, Sweden, to work out a plan of attack for development of the Code.
