FDA Foods and Veterinary Medicine Science Research Conference

October 25-26, 2016
Silver Springs, MD

FDA Centers of Excellence Annual Meeting

October 27, 2016
College Park, MD

Each year the FDA hosts a meeting at the Center for Food Safety and Applied Nutrition (CFSAN) for the four FDA Centers of Excellence (COEs): IFSH, JIFSAN, NCNPR and WCFS. This meeting facilitates interactions among the COEs and scientists from CFSAN. Rob, Michele and Linda each presented brief research updates at this year’s COE meeting in College Park. Michele also attended the 6th Annual FDA Foods and Veterinary Medicine Science Research Conference, where she presented a poster entitled Screening and enumerating Salmonella and pathogenic STEC in raw animal manure used as a soil amendment: data collection for risk assessment. Co-authors are Peiman Aminabadi (WCFS UCD), Yuhuan Chen (CFSAN), David Ingram (CFSAN), Kali Kniel (University of Delaware), Thais de Melo Ramos (University of Delaware), Steven Duret (CFSAN), and David Oryang (CFSAN). This research validated a screening and enumeration method to detect and quantify Salmonella and Shiga toxin-producing Escherichia coli (STEC) from poultry and cattle manure samples, respectively. To reduce labor and cost of doing large numbers of samples, a streamlined flow process was developed by using a combination of presence/absence screening followed by most-probable-number determination. The complete abstract is available here.




4th Asia-Pacific International Food Safety Conference and 7th Asian Conference on Food and Nutrition Safety 

October 11-13, 2016
Penang, Malaysia

Linda Harris gave the International Association for Food Protection Keynote Lecture “Low moisture foods:  food safety challenges and opportunities” to 400 attendees at the Asia-Pacific International Food Safety Conference, which is a regional conference that aims to address the latest trends and issues in food safety across the Asia-Pacific region. It is sponsored in part by the IAFP. The program is available here.






Multi-Regional Risk Analysis Of Farm Manure Use and Soil Health 

Alda Pires and Michele Jay-Russell will lead a project to determine the time needed between application of untreated manure and harvest of food crops to minimize risk from pathogens. The project is funded through a USDA Organic Research and Extension Initiative (OREI) grant award of $1,999,848. These studies are needed to develop guidelines and best practices for using manure to supply nutrients while minimizing risks in organic crops. In addition to UC Davis, project collaborators include the University of Minnesota; University of Maine; USDA Agricultural Research Service, Beltsville Agricultural Center; USDA Economic Research Service, Resource and Rural Economics division; Cornell University; and The Organic Center. The USDA grant award is number 2016-51300-25724. Read more here. The position description may be found below.




CPS Awards 10 New Research Grants

Linda Harris received one of 10 research grants awarded by the Center for Produce Safety (CPS). Harris’s grant is entitled Characterization and mitigation of bacteriological risks associated with packing fresh-market citrus. The awards announced on October 18, 2016, are valued at over $2 million. According to CPS, “the awards are for research projects directed at answering critical questions in specific areas of food safety practices for fruits and vegetables; pre-harvest, harvest and post-harvest handling; and food safety and the environment. The objective is to provide the produce industry with practical, translatable research data that can be used at all levels of the supply chain”.




Acidified Foods Manufacturing School 

October 5, 2016
Davis, CA

The Acidified Foods Manufacturing School is offered through North Carolina State University in a combined on-line and in-person format. Segment 1 is offered on-line, and must be taken before Segment 2. Segment 2 was offered in Davis in October, organized by Linda Harris, and had 10 attendees. It will be offered in Davis again in September 2017. More information is available here.




Basic and Advanced HACCP Workshops

October 17-19, 2016
Davis, CA

Linda Harris co-taught the HACCP workshops with Nina Parkinson and Michael Jantschke.
These courses are taught once a year through UC Davis Extension, and designed to meet the requirements of USDA, FDA Seafood, and FDA Juice HACCP regulations, and are applicable to other types of food manufacturing establishments. The courses are accredited by the International HACCP Alliance.

NAU-UC Davis One Health Symposium

October 10-11, 2016
UC Davis

The semi-annual symposium for the joint Nanjing Agricultural University (NAU) – UC Davis One Health Center for Food Safety and Animal Health was held on the UC Davis campus, October 10-11. The 2-day symposium, hosted by WIFSS, included curriculum development, faculty and graduate student exchanges, and graduate student research projects.

NAU was led by Vice-President Jianjun Dai, and the College of Veterinary Medicine’s Dean, Jiyong Zhou. Joining Dai and Zhou were professors Zhihong Xin, Huochun Yao, Jiarong Xu, Yong Sam Jung, Yingjuan Qian, and Gaowen Yang.


John Angelos, Amanda Arens, Heather Johnson, and Bennie Osburn, from the School of Veterinary Medicine-WIFSS, met with Vice President Dai, Dean Zhou and Professor Qian, to discuss curricular development for courses that can serve as part of the developing One Health for Food Safety program.

Bennie Osburn, Chris Brunner, Jenny Chen, Xinbin Chen, and John Angelos, served as coordinators for the symposium.

Delta Flood Safety Fair

October 22, 2016
Isleton, CA

DCP LogoMichael Payne, dairy outreach coordinator with WIFSS, was on-site for the Delta Protection Commission’s Delta Flood Safety Fair, held in Isleton, CA, on October 22. The fair was held in concert with California Flood Preparedness Week. The commission declared a week in October to be the annual Delta Flood Preparedness Week.

WIFSS co-sponsored the fair booth with the School of Veterinary Medicine’s Center for Equine Health.  Payne answered fair goer’s questions about flooding and livestock and equine response and recovery, and distributed brochures on Flooding & Livestock Owners, and Flooding & Equine Owners.
















Nora Sampling Nora Navarro-Gonzalez, postdoc in Michele Jay-Russell’s lab, wrote an article for Atlanta BEST, an online magazine, about utilizing skills she learned in UCD’s FUTURE program (Frontiers of University Training to Unlock the Research Enterprise) while attending the IAFP Annual Meeting this summer. FUTURE is funded by a BEST award (Broadening Experiences in Scientific Training, a program of NIH), and is intended to empower graduate students and postdoctoral fellows to better develop their own career paths. The article, entitled What the FUTURE Taught Me, was published in the summer issue and may be found here.






Postdoctoral Scholar Position in Food Safety and Organic Agriculture
