SUMMARY
Wisconsin dairy professionals (n = 165) were surveyed during late 2001, using a mailed questionnaire. The survey was composed of questions regarding personal work characteristics, impression of a team-based milk quality improvement program (Milk Money) and opinions about milk quality issues.  The response rate was high (78.8%), and respondents comprised veterinarians (n = 42), extension agents (n = 35), dairy plant field representatives (n = 21), vocational agricultural instructors (n = 17) and others (n = 15). Responders were experienced and worked with herds that were representative of  Wisconsin dairies. Most (66.7%) dairy plant field representatives spent more than 50% of their professional time working on milk quality issues, whereas the majority of other responders spent < 10% of their professional time working with this issue. Most responders (88.3%) agreed that working with other consultants is an effective way to improve milk quality. Common barriers to improvement of milk quality on farm were the existence of too many other problems (54.6%) and few incentives for production of high quality milk (47.7%).  Additional on-farm training programs (23.9%) and “more time” (21.5%) were cited as resources needed for implementation of farm-based milk quality programs.  All responders agreed that bulk milk somatic cell counts (BMSCC) and milk quality premiums were important for dairy farm profitability.  Most (78.5%) responders agreed that the current U.S. BMSCC regulatory limit was too high. Responder groups differed in their opinions regarding critical issues for improvement in milk quality and the willingness of farmers to pay for specific milk quality services.

SUMMARY
Company food safety needs must be evaluated in order to implement successful food safety training. Customizing a program to address unique situations and needs in the food industry requires studying day-to-day food safety operations and worker food safety behaviors.  One problem with most inspection methods is that they alter the behaviors being studied. To develop a less obtrusive approach, we examined the useful-ness of an observation method called the Worker-Experience Protocol (WEP) in conducting a needs assessment in a food production setting. The objectives of this paper are to (1) outline the steps in the WEP, in which a person unconnected to either the regulatory system or the food company served as a ‘worker’ in order to make direct observations of company operations and worker behaviors; (2) compare the findings from this observation protocol with those of focus groups conducted with workers at the same companies; and (3) outline the unique insights that WEP provides for food safety needs assessment. Both methods highlighted current strengths and weaknesses that are reported under the following major themes: Implementing proper food safety practices; adequate plant/farm sanitation; worker food safety behavior; and communication channels. Whereas the WEP identified the physical situation and personal behaviors and interactions that might contribute to problems, the focus groups illuminated the workers’ attitudes and commitment and reasons why problems occur.  Although both methods provide valuable information for designing food safety programs, the WEP offers a fast, inexpensive method of gaining a well-rounded impression of worker and management actions and interactions related to food safety at a given time or at repeated time points. WEP also avoids the short-term behavior modification that often occurs during an audit or plant inspection. Food professionals could use this protocol to obtain valuable information regarding food safety needs in their operations.

SUMMARY
A study of 40 school foodservice operations assessed the effectiveness of cleaning and sanitation of five food contact surfaces, including work tables/counters; cooking equipment such as mixing bowls or steam-jacketed kettles; and serving trays and equipment surfaces that could cross-contaminate food, such as refrigerator or freezer handles and handwashing sink handles.  Aerobic plate count (APC), Enterobacteriaceae, and Staphylococcus aureus analyses were conducted for all samples.  The following microbial counts were used as standards for cleaned and sanitized food-contact and non food-contact surfaces:  APC < 1.3 log10 CFU, Enterobacteriaceae count < 1.0 log10 CFU, and Staphylococcus aureus < 1.0 log10 CFU per sample.  Four facilities met standards for all five surfaces for each of the three tests.  Fewer operations met the standard for APC than for the other two tests, and refrigerator or freezer handles failed to meet the standard for APC in nearly two-thirds of the operations. Results suggest that microbial standards for surface sanitation are attainable in schools and that school foodservice employees need to receive training and supervision to ensure proper handwashing and appropriate cleaning and sanitation procedures and to limit cross contamination.
