چکیده انگلیسی:
National governments are moving to integrate risk analysis frameworks into food safety management systems at
the country level. However, this process is less advanced in developing countries. In this context, the Chilean
Livestock and Agriculture Service (SAG), Food Quality and Safety Agency (ACHIPIA) and the University of
Nebraska-Lincoln (UNL) collaborated on a project to control generic Escherichia coli and Hepatitis A virus (HAV)
contamination in both fresh and frozen raspberry products destined for export. The objectives of this study were
to 1) identify along the raspberry supply chain the most influential factors of E. coli and HAV contamination in
the final products; and 2) evaluate the efficacies of possible interventions to control these influential factors. To
achieve these objectives, a unified quantitative model of microbial contamination in raspberries was developed
to describe the impact of factors in a continuum from the farm to the destination of importation on E. coli/HAV
contamination in fresh and frozen raspberry products. Multiple surveys were conducted to obtain countryspecific
data on current common practices of producing and processing raspberries in Chile for inputs into the
simulation model. The model estimated mean bacterial loads of−1.64 and−5.46 logCFU/g for E. coli and mean
viral loads of −6.45 and −6.51 logPDU/g for HAV in fresh and frozen raspberries, respectively. Sensitivity and
scenario analyses indicated that reduction of E. coli contamination in the end products can be effectively
achieved by improving the quality of water used for pesticide application, as well as by controlling the transport
and storage time and temperature along raspberries supply chain. By contrast, to control HAV contamination in
the end products, efforts should be focused on improving the hygiene practices of berry handlers on the farm and
at the packing plant. This project provides straightforward recommendations for Chilean food safety authorities
to effectively prioritize their financial and human resources to proactively prevent microbial contamination in
raspberries. Moreover, this project provide a framework that can be extended to other countries to promote
capability building for applying risk-based food safety management systems for public health protection.
