Non Technical Summary
Although many diseases have been documented from consumption of raw (unpasteurized) milk and raw milk cheeses, the risk of consuming these products compared with other foods including those made from pasteurized milk, has not been fully explored. The proponents of these products quote sources supporting their healthfulness and nutritional quality, including being a barrier to enteric disease infections and allergenic reactions. These are usually refuted by public health personnel as unfounded, but little in the way of dialog takes place in a public forum on the science of both positions. Since there will always be a small proportion of any population who will avidly seek sources of raw milk or raw milk cheese, it is important to understand the main reasons for these choices, and minimize the practices with the highest risk. There are three groups of people that wish to have the choice of obtaining these products: 1) farming families where the source is readily available; 2) nationalities where these products are associated with their culture, and also especially migrants when they move away from that culture; 3) "yuppies" or young urban professionals, who also may be members of the organic and natural foods movement and identify with small rural dairy producers. The prime aim of this conference is to share the science that relate to these products, what more has to be researched to reduce the risk of illness, and to broadcast the presentations and discussion widely for consumers so that they can make wise choices.

Goals / Objectives
The output of this grant is a conference and subsequent follow-up. The proposed conference will consist of a multidisciplinary dialogue with a primary North American focus, to explore the consumer demand and production practices for raw milk and raw milk cheese, and how various jurisdictions manage, if at all, their sales to minimize the risks of disease. It also aims to address any gap in knowledge by seeing if there are more recent studies on the knowledge, attitudes, and practices of raw milk producers and consumers, and potential on-farm hygienic improvements and decontamination procedures besides pasteurization. Topic areas to be discussed include the existing surveillance mechanism to detect diseases arising from these products and determine the risk of infection by consumers; the regulations, standards and enforcement actions to limit the sale of these products; analyzing the arguments by proponents for having the choice to consume these products; and risk communication and education approaches to limit disease occurrence.
Project Methods
The conference will bring together speakers and audience with an interest in raw milk and raw milk cheese but these interests may be at cross purposes. The proponents want ready access to these products and the regulatory agencies want to limit the risk of disease by banning or otherwise controlling sales. The expected dialog should generate information that will help people make decisions, but the intended information will be offered on a broader scale by using electronic media such as web pages, i-pods, or other means of delivery with ways of measuring response by this larger audience. A steering committee will help with conference agenda.

Outputs
OUTPUTS: The PI worked with the American Cheese Society during 2011 to have speakers on raw milk cheese both from a public health and consumer perspective and a producer's one in a special raw milk cheese educational track. The conference was held from August 4-6, 2011 in Montreal. There were national and international speakers from the production and government oversight perspective, supplemented by academic research. Topics covered were: Health Benefits, Biodiversity Factors, Controlling Pathogens, Raw Milk Cheese Trends Around the World, Raw Milk Cheese Today, Quebec's Raw Milk Cheeses, Regulator's Research and Thinking (USA and Canada). The target audience was primarily cheese and milk producers, but also academic researchers, policy-makers, and lawyers on health risks and benefits. About 500 registrants attended. PARTICIPANTS: Ewen Todd and Jef Richards, chair of Advertising, Public Relations and Retailing, organized the meeting content and the follwing particpants. Carol Terracina Hartman, Ph.D. candidate in the Media and Information Studies program, College of Communication Arts and Sciences, Michigan State University. Ryan Fewins-Bliss, Fewins-Bliss Consulting, non-profit organization, Ph.D. candidate in the Media and Information Studies program, College of Communication Arts and Sciences, Michigan State University. Brigitte Barlow, Media & Information Studies PhD student teaching Consumer Behavior, College of Communication Arts and Sciences, Michigan State University. Nora Weiser, Executive Director, American Cheese Society. TARGET AUDIENCES: Primarily raw milk and pasteurized cheese and milk producers, who are members of the American Cheese Society. Some academics and policy-makers were also present. Lawyers who specialize in tort law cases were also in attendance. PROJECT MODIFICATIONS: Attempts to have the conference funds in other venues were not successful, and neither the US FDA nor USDA wanted to be a co-sponsor of any conference on this topic (or the International Dairy Federation or other food safety societies). The review panel wanted to have a proponent involved in raw milk or raw milk cheese production and this was done through the American Cheese Society, who were very pleased to be a collaborator and felt it enhanced their 2011 conference.

Impacts
The presentations were well received by those attending each of the 7 sessions from Thursday to Saturday. Producers generally made both pasteurized milk cheese and raw milk cheese and were concerned about the risks of illness from their products. Cheesemakers voiced their interest in learning more of the science to reduce their risks of contaminating their products that could lead to a foodborne illness, with potential legal action and loss of business. Thus, the presentations addressing current research and control strategies among the different jurisdictions and what more can to be done to reduce the risk further were appreciated. The presentations and discussion on current and future regulations were particularly appreciated as this is a sensitive area affecting their sales and reporting of associated illnesses, and it lets the cheesemakers better prepare for marketing their products. Since new regulations are be considered by both Health Canada and The US FDA, there were many questions and concerns about mandatory storage periods for raw milk cheese. Both the speakers and the audience came with open minds and recognized that consumer choice and risk of illness are components that are always going to be areas of tension. The mix of speakers was critical to the success of these sessions to allow a meaningful dialogue and discussion, and not come with stated fixed positions, although they had preferences. The impact will be more attention by cheese producers to the risks of cheese production (both raw and pasteurized milk) as producers review existing processes and explore new product areas.

Progress 09/01/09 to 08/31/10

Outputs
OUTPUTS: Conference not held yet, but a partner has been found with the American Cheese Society for a link to the next annual conference to be held in Montreal in August 2011. PARTICIPANTS: Ewen Todd and Elliot Ryser at MSU will be involved and Ewen Todd as PI will coordinate the conference planning with the American Cheese Society. TARGET AUDIENCES: Policy-makers, cheese and milk producers, academic researchers on health risks and benefits as well as those involved with behavioral studies. About 500 registrants are expected to be at the American Cheese Society conference. Short papers are expected to be published by the speakers to reach a wider audience. PROJECT MODIFICATIONS: Focus more on raw milk cheese at the conference rather than raw milk, although raw milk is an ingredient for the cheese. One key aspect will be the survival of pathogens in different kinds of cheeses.

Impacts
None.

Progress 09/01/08 to 08/31/09

Outputs
OUTPUTS: Steering committee being formed, delayed because of conflict of interest by potential collaborators, e.g., International Dairy Foods Association and Food and Drug Administration who will not work with anyone promoting consuming of raw milk. PARTICIPANTS: PI Todd is actively seeking members to serve on the Advisory Committee. TARGET AUDIENCES: The Steering Committee will decide who the audience is depending on where the meeting is held and how much funds we have, but likely to include public health officials and proponents of raw milk/raw milk cheese consumption. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
