The Sponsorship Prospectus for the 2021 Fresh Produce Safety Conference is available now.
The Fresh Produce Safety Conference will be held in Sydney and online on 18 August 2021. Themed Future Directions for Produce Safety, the conference brings together key industry professionals to explore issues and research around fresh produce food safety.

US – Center for Produce Safety: A handful of Cyclospora cayetanensis outbreaks tied to U.S.-grown produce since 2018 have prompted several researchers to begin looking at possible domestic sources of the pathogen and potential industry risks. Read more.
See a short video on this research, Investigating Sources of Cyclospora in the Southeastern US, here.
AU – The paper ‘Persistence of Human Pathogens in Manure-Amended Australian Soils Used for Production of Leafy Vegetables‘ is now available online in a special issue of the journal Agriculture. The paper, authored by Dr Jenny Ekman and others, has been published as part of the research undertaken for the Hort Innovation project ‘Pathogen Persistence from Paddock to Plate’. Hort Innovation, together with the vegetable industry, completed a study on the survival of human pathogens in soil and irrigation water, and on leafy vegetables. The project was led by the Fresh Produce Safety Centre, in conjunction with Applied Horticultural Research, Freshcare and the University of Sydney.

Food Safety News: The World Health Organization (WHO) has identified key priorities to improve food safety in the next five years in South East Asia.
The Framework for Action on Food Safety in the WHO South-East Asia Region covers 2020 to 2025 and has guidance for authorities across the food chain and those involved in food safety emergencies, preparedness and response. Several countries are included. More here.

The Center for Produce Safety in the US has prepared key learnings summaries of its Annual Research Symposium, with five sessions held over June and July 2020.
The full set of Key Learnings from the CPS Research Symposium is here. The following text is drawn from the CPS Key Learnings:
During Session 1 held on June 23, 2020, the Symposium explored the use of computer-based modelling to help address two burning issues for the produce industry: understanding potential Listeria growth and persistence in whole produce commodities and the development of sampling strategies to support the validity of assumptions surrounding microbial testing needs and design of acceptable protocols (Key Learnings Session I).
In Session 2, the Symposium expanded the knowledge base on Listeria monocytogenes and its persistence and growth on specific commodities and fresh-cut products and examined novel methods to control Listeria growth on food contact surfaces (Key Learnings Session II).
In Session 3, the Research Symposium explored projects that took wholistic, systems approaches to solving challenges with pest intrusion into leafy greens fields, pathogen transference on co-managed farms and the impact of traits associated with concepts of soil health on pathogen persistence. It also examined Cyclospora presence in the irrigation canal systems in the Yuma, AZ production region (Key Learnings Session III).
Session 4 featured the use of genomics and metagenomics to address challenges in identifying new or revisited indicators and index testing-targets of human viral pathogens that may ultimately be used in the produce industry, the distribution and relatedness of Listeria species in the U.S., and the use of that information to better understand source-risk related to facilities and product, identification of competitors of Listeria monocytogenes that might control that organism in composts, and build our knowledge base of bacterial pathogen persistence and rates of genetic diversification in the Yuma and Salinas vegetable production regions (Key Learnings Session IV).
Session 5 featured research describing the “die-off” rates of human pathogens in agricultural water from three locations around the world, the persistence of pathogens in shade-house production environments, pathogen persistence in wash water systems and the potential roleof damaged cells to contaminate washed products, the efficacy of irrigation water sanitation and the potential role of sediments in canal systems as reservoirs of human pathogens (Key Learnings Session V).Read Article →

foodprocessing.com.au: Researchers at the University of Illinois College of Agricultural, Consumer and Environmental Sciences (ACES) decided to look at how viruses could stick to the surface of 24 common salad vegetables. They expected to establish that the small virus particles could â€˜hideâ€™ in the rough structures of the cuticle, the waxy layer that protects the plant against diseases and reduces water loss.Read Article →
