NEHA 2018 AEC Conference | June 25-28, 2018, Anaheim, CA
|
|
|
|
|
Michele Jay-Russell co-presented with Mary McGonigle Martin on The Contemporary Raw Milk Movement at the annual National Environmental Health Educational (NEHA) Annual Education Conference (AEC) held in conjunction with the HUD Healthy Homes Conference. Jay-Russell presented an environmental health perspective on the state-of the-science related to raw milk food safety risks and health benefit claims. McGonigle-Martin shared a personal experience with E. coli O157:H7 infection, and complications from hemolytic uremic syndrome. She also reviewed possible societal and economic reasons for the increasing number of foodborne illnesses in the U.S. linked to raw milk since the early 2000’s, including the concomitant efforts by raw milk advocates to loosen regulations and increase access to unpasteurized dairy products. The next AEC conference will be held in Nashville, TN on July 9-12, 2019.

All Hazards Planning and Preparedness Courses | July 10-13, 2018, Burlington and Kelso, Washington
|
|
Tracey Stevens and Mike Payne were in the state of Washington during the second week of July conducting all hazards disaster preparedness courses. On July 10 they were in Burlington, WA conducting a course in AWR 328: All Hazards Preparedness for Animals in Disasters. On July 12 and 13 they were in Kelso, WA, conducting AWR 328 and MGT 448: All Hazards Planning for Animal, Agricultural, and Food Related Disasters. The timing for the courses was relevant as wildfires were in close by locations.
MGT 448 and AWR 448 are sponsored by the Department of Homeland Security (DHS), the Rural Domestic Preparedness Consortium (RDPC), and WIFSS. DHS gives certificates to those completing the course which can be used as proof of training to become part of a disaster team responding to disasters.
The management level course MGT 448 provides emergency planners, community leaders, veterinarians, animal control personnel, government and non-government agencies and public health agencies with the background information needed to participate in the development of disaster response plans that could be included within the existing operational area.
The awareness level course AWR 328 provides a forum for individuals from many different perspectives to meet together and think through what would be needed in order to effectively respond to a disaster that impacts animals in a rural region in the U.S.

Carlo de Olim interviewed Michele Jay-Russell for the 8th episode of his podcast series, The Poison Terminator. They discussed the topic, Important Facts to Know about the Salmonella Outbreak Linked to Pre-Cut Melons including how salmonellosis is diagnosed, treated and what to do if there is a food recall. The podcast series aims to have guests who are experts working in poison control centres, universities, governmental agencies, and citizens promoting healthy practices in their communities.

Dairy Facilities Security Workshop | June 27, 2018, Davis, CA
|
|
|
Dean Michael Lairmore, School of Veterinary Medicine, UC Davis, welcomed participants to a workshop held on the UC Davis campus on June 27, 2018. Attendees at the dairy roundtable workshop included dairy producers, and employees of the U.S. Department of Homeland Security, FDA, and USDA. The FBI workshop was hosted by the vet school and WIFSS. The CDFA and the California Dairy Quality Assurance Program, participated in the program.
Michael Payne gave a presentation on the vulnerability of the dairy industry to criminal acts.
Protecting the food supply requires a robust public health, law enforcement, regulatory, and private sector partnership capable of preventing, detecting, and responding to intentional food borne outbreaks. The objectives of the workshop and table top exercises was to 1) improve incident response planning, 2) increase industry awareness of food defense concepts, 3) identify and implement best practices for food defense, and 4) strengthen partnerships and promote awareness of roles, responsibili ties, authorities, and resources of each stakeholder.

WCAHS Seminar | June 6, 2018, Davis, CA
|
|
|
Rob Atwill presented on Preventative Interventions to Reduce Dairy Worker Infection as part of a series of monthly seminars hosted by the Western Center for Agricultural Health and Safety (WCAHS). Atwill addressed a combination of veterinary and medical school students and faculty, as well as industry professionals, on the potential risks and remedies associated with Cryptosporidium on dairies. |

Cookson Beecher interviewed Michele Jay-Russell for a story in Food Safety News entitled No Quick or Easy Answers for Using Raw Manure on Food Crops. The article explores the upsides and downsides of raw manure use in agriculture, and implications for fresh produce growers under the Food Safety Modernization Act, (FSMA) Produce Safety Rule. Samir Assar and Dave Ingram from FDA’s Division of Produce Safety were also interviewed. Assar and Ingram work closely with WCFS scientists to use data generated from our research to inform policy.

Patterson, L. N. Navarro-Gonzalez, M.T. Jay-Russell, P. Aminabadi, E. Antaki-Zukoski, and A.F.A. Pires. 2018. Persistence of Escherichia coli in the soil of an organic mixed crop-livestock farm that integrates sheep grazing within vegetable fields. Zoonoses Public Health. doi.org/10.1111/zph.12503
This is the first of several studies being conducted by the Jay-Russell and Pires Laboratories in a unique collaboration with commercial and experimental mixed crop-livestock operations. Major findings included:
- Mixed crop‐livestock farms integrate livestock and crops using animals to graze crop residues and/or cover crops.
- As sheep are known to harbor pathogenic E. coli, generic E. coli can be used as a surrogate to study the persistence and transfer of STEC from livestock to soil to produce. Understanding this relationship will help re‐duce microbial food safety risks associated with live‐stock raised on mixed crop‐livestock farms.
- Developing and validating research‐based waiting periods between grazing and harvest is important to inform best practices for farmers, food safety regulators and policy makers to ensure a safe food supply.

Best of Luck to Melissa Partyka!
We are wishing Missy Partyka a fond farewell as she embarks on a new journey at the University of Auburn with the Sea Grant Oil Spill Outreach Team. After many years of working on water quality for the Atwill Laboratory and WCFS, she has earned nation-wide recognition as a key player in the development of water quality standards that can be used for helping establish the final recommendation for FDA’s FSMA Produce Safety Rule. She played an integral part in the study design of multiple projects, data management and analysis, and spearheading multiple publications.
Missy was very important for the WIFSS Outreach and Training program as she participated in a number of outreach programs including those involved in a review and recommendations for the produce outbreak investigation series, training of students, and working with faculty and students from China attending our One Health conferences at Davis. The conference participants always appreciated her hands-on training in water sampling techniques and record keeping methods. In addition, Missy was invaluable in her volunteer support during Farm-to-Fork festivities in Sacramento each September where hundreds passed by the exhibit. We wish her the best of luck in her new Outreach endeavors with the Sea Grant Oil Spill Outreach Team and know that they will benefit from her enthusiasm, creativity, and excellent ability to translate and share research findings.
