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 role
of 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).

Michigan State University: Water sampling to meet federal on-farm food safety guidelines can be confusing. This article helps eliminate some confusion about taking and submitting a water sample.
FPSC: Can the FDA Food Safety Modernization Act (FSMA) provide a framework to improve practices and boost exports for Chilean raspberry producers?
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 ‘hide’ in the rough structures of the cuticle, the waxy layer that protects the plant against diseases and reduces water loss.
Journal of Food Protection: Tomatoes have been implicated in various microbial disease outbreaks and are considered a potential vehicle for foodborne pathogens. Traceback studies mostly implicate contamination during production and/or processing. The microbiological quality of commercially produced tomatoes was thus investigated from the farm to market, focusing on the impact of contaminated irrigation and washing water, facility sanitation, and personal hygiene. A total of 905 samples were collected from three largescale commercial farms from 2012 through 2014.
There’s a lot of people responsible for grower, packer or processor quality assurance and food safety who are not technically trained in QA and food safety. That’s just a fact of life that reflects the size, structure and necessities of many fresh produce businesses – small, family and tight. It’s also the reason why some QA standards and customers insist on a minimum level of training for the person(s) responsible for managing food safety in the business, with some now also providing the required training.

Dr Bob Whitaker & Dr Jim Gorny from the Produce Marketing Association have provided a summary of 10 key lessons from the 2014 US Centre for Produce Safety (CPS) fifth annual reseach symposium.
Brief Report, CPS Research Symposium 26 and 27th June 2013 ,Wegman’s Conference Centre Rochester, NY State.
The CPS at the University of Davis has been very supportive of the initiatives in Australia to establish an affiliated Fresh Produce Safety Centre. Over the past year they have very generously shared their research outcomes, they have given presentations to our industry, and this year invited Australian researchers to apply for research grants to work collaboratively with US scientists on issues important for the Australian fruit and vegetable industry.
