Thesis Title
A food chain approach to control of shiga-toxin producing E. coli in New Zealand

Shiga toxin-producing Escherichia coli (STEC) are a zoonotic pathogen that can cause bloody diarrhoea and acute kidney failure, particularly in young children. Cattle are a well-recognized STEC reservoir, and previous research has identified living near cattle and contact with their faeces as an increased risk for human infection. The New Zealand meat industry undertakes testing to ensure that veal beef exports to some international markets are free of STEC. Springer's thesis provided novel data and interpretation for the prevalence and transmission of the ‘Top 7’ STEC of dairy calves in New Zealand on a farm and national level, while applying genomic analyses to interpret New Zealand STEC on an international level. The data can be used for future risk assessment and to protect public health and safeguard the trade of New Zealand beef around the world.
