Goals / Objectives
Recent outbreaks of pathogens such as E.coli 0157:H7 in fresh produce have elevated the need to revise the NRCS publication, "Waterborne Pathogens in Agricultural Watersheds." This NRCS publication remains one of the most comprehensive monographs on what are the current waterborne microbial threats of public health concern, monitoring methods, for these microbial risks, and suggested beneficial mgmt practices for landowners to use to mitigate these risks. There is a very strong demand for a revised monograph to address these issues, especially in agricultural regions that have a mixture of animal agriculture and leafy green produce given the concern of pathogen contamination of minimally treated produce commodities such as lettuce and spinach. Dr. Atwill will revise the publication to include updated and new information since the publications inception, including information on pathogens and vegetable production, and pathogens and animal diseases of interest (such as Johnes disease). Dr. Atwill will ensure that peer reviewed references are updated and likages to existing NRCS and other agency publications are enhanced.
Project Methods
Cooperator will review existing NRCS document, assess the capacity of the document to meet the needs of the Agency in working with conservation issues involving pathogens, and then re-write the document to reflect new or increased knowledge about the role of water borne pathogens on animal diseases, food safety, and water quality. Cooperator will coordinate with NRCS personnel to insure applicability of material to NRCS conservation practices. Cooperator will coordinate with NRCS national and CA state staff to insure applicability of material to NRCS field staff. NRCS will provide review of materials generated by cooperator. NRCS will provide printing, duplication, and dispersal of final product.

Outputs
Target Audience: Our target audience are land owners, agricultural managers, livestock operators, public and private resource managers, public health officials, and water quality regulators involved in the issue of waterborne pathogens in agricultural watersheds. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? As stated in the previous report, the purpose of this project was to create materials that would aid the NRCS internally to train agency staff on issues of water quality in agricultural landscapes. Additionally, information was made available to the agricultural industry, resour management agencies, cooperative extension offices, and the general public through a series of workshops and invited talks. For example: (1) Atwill, E.R. Invited Speaker. Epidemiologic analysis and risk management practices for reducing E. coli in irrigation source water supplies and distribution systems. 2010 Fresh Summit: Produce Marketing Association. Orlando, Florida. October 15-17. (2) Atwill, E.R. Invited Speaker. Livestock, range management, and waterborne pathogens. Tuolumne County Range Water Forum. Sonora, California. February 15.

How have the results been disseminated to communities of interest? Portions of the technical report and web-based modules have been incorporated in workshops and presentations mentioned above. The published review and the web-based course have both been made available through an NRCS portal. An Introduction to Waterborne Pathogens in Agricultural Watersheds Web Based NRCS-NEDC-000282 Revision: 1 - 12/3/2012 02:04 PM America/Los Angeles Description: This course is an internet based training session centered around eleven modules presented in three parts. Each part can be taken in about one hour. The course provides an introduction to waterborne pathogens in agricultural watersheds and provides information on common pathogens, their fate and transport, their importance to agriculture, and their control. The course introduces many different types of pathogens, many concepts, and relates these things to NRCS conservation practices What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? This technical note, which has been submitted for peer-review, is one of the most comprehensive and practical guidance manuals for the biology of waterborne pathogens; specifically why they occur in our US agricultural watersheds, and which beneficial management practices can effectively reduce these waterborne hazards. The NRCS substantially contributed to this project by funding the work and then organizing and conducting a nation-wide peer-review of the materials and teaching module.

    Progress 01/01/09 to 12/31/09

    Outputs
    OUTPUTS: We have finished the second year of a three year project where we are writing a moderately technical note on waterborne pathogens in agricultural watersheds. A 139 page draft of this technical note has been completed and the first round of NRCS peer review completed. In addition, we have developed 12 web-based courses that will accompany the technical note suitable for the agricultural scientists, land owners, and resource managers, which has also been peer-reviewed. We have conducted a number of workshops and seminars to agricultural and regulatory community regarding waterborne pathogens, vertebrate sources, mechanisms of fate and transport, and long list of beneficial management practices for mitigating these public and animal health hazards Examples of talks would include: (1) Dr. Rob Atwill as speaker. Ambient conditions and monitoring for livestock associated pathogens and indicators in California waterways. Water Quality, Range, Pasture, and Livestock Management Workshop. Woodland, California.
