Restaurant industry preparedness against intentional food contamination: results of a South Carolina survey.

Food safety and food defense are both responsibilities of public health agencies. Food safety practices within restaurants are regulated by state and local public health laws based on the US Food and Drug Administration Model Food Code. However, little is known about preemptive practices against intentional food-borne outbreaks within restaurants. The researchers administered a survey to a 50 percent random sample of South Carolina's restaurants, a state that relies heavily on tourism and the restaurant industry for its economic well-being. The survey received a response rate of 15 percent. The food defense practice items fall under three functional categories: employee management and training practices; vendor and delivery-related practices; and physical facilities and operational security practices. This study presents the results, classified by geographic region. Findings indicate some key areas of vulnerability that need attention to protect the public from mass food outbreaks due to intentional contamination. Of concern, there is much variation in practices by geographic region. On the basis of the survey, recommendations are made to improve restaurant preparedness against food-borne outbreaks from terrorism and malevolent contamination.

Preventing intentional food contamination: a survey to assess restaurant preparedness.

In the age of preparedness, public health agencies are concerned with intentional acts of food contamination in restaurants, in addition to food safety. Food safety consists of applying standard norms of practice and infrastructure, which, if violated, cause food-borne illness. In contrast, food defense requires an institutionalized mindset of informed alertness to unusual variations from the norms, combined with preemptive practices best suited to each restaurant. Therefore, while food safety lends itself to regulation to ensure standard practices, food defense is best served by advisory guidelines for autonomous application, preserving the restaurant industry's core values of hospitality and customer service. To address this challenge, public health agencies need survey tools that can yield action-relevant data on the knowledge and practice gaps in food defense preparedness and on educational messages and support services to be developed for maximum impact potential. This article presents a mail survey instrument, developed using qualitative research to ensure content and face validity. Instrument development involved drafting the survey on the basis of expert consultations, validating its content by using focus groups (representing all restaurant categories and geographic regions), and ensuring face validity through cognitive interviews. The resulting survey remains sensitive to the hospitality industry while encompassing all vulnerable points.

Importance of prudent antibiotic use on dairy farms in South Carolina: a pilot project on farmers' knowledge, attitudes and practices.

Inappropriate use of antibiotics in humans and animals contributes to decreased antimicrobial susceptibility in bacteria of medical importance. Resistant bacteria being transferred from animals to humans are causing public health concern. In-person interviews were conducted with 20 dairy farmers in rural counties of South Carolina to determine farmers' knowledge and attitudes about prudent antibiotic use among livestock. Four focus groups (n = 22) were also conducted to ascertain farmers' specific information needs about proper antibiotic use. Survey results showed that participants (100%) typically determined a need for antibiotic treatment using symptom assessment and reported following some form of operating procedures regarding administration of antibiotics. Few farmers (32%) had actual written antibiotic protocols. Preferred information sources about antibiotics were veterinarians (100%) and other dairy farmers (50%). Most farmers (86%) were not concerned that overuse of antibiotics in animals could result in antibiotic resistance among farm workers. Qualitative analysis of focus groups revealed significant barriers to following proper antibiotic procedures including limited finances and lack of time. The need for bilingual educational resources for Hispanic/Latino dairy workers was expressed. Desired formats for educational materials were posters, flowcharts, videos, and seminars. Education of South Carolina dairy farmers by veterinarians and public health professionals on the appropriate use of antibiotics in dairy cattle is needed to ensure antibiotic effectiveness in both animals and humans.

Urinary estrogen metabolites, prostate specific antigen, and body mass index among African-American men in South Carolina.

INTRODUCTION: Estrogen metabolites have been linked to risk of breast cancer, and we were interested in whether they are associated with prostate specific antigen (PSA) and other factors associated with prostate cancer. African-American (AA) men in South Carolina have among the highest prostate cancer rates in the world, and thus provide an ideal population in which to investigate this hypothesis. METHODS: We recruited AA men attending prostate cancer screenings in and around Columbia, South Carolina. Because very few men had elevated PSAs, we restricted our study to the 77 men whose PSA was below the cutpoint used by the screening program to indicate need for diagnostic workup. These men provided spot urine samples and answered demographic and lifestyle questions including self-reported body weight, height, exercise, tobacco use, medications, cancer history and age. Levels of urinary 2-hydroxyestrone (2-OHE1) and 16alpha-hydroxyestrone (16alpha-OHE1), and their ratio (2/16) and blood PSA levels were determined. RESULTS: After adjusting for a statistically significant interaction between age and BMI, we found a reduction of 14.2% in 2-OHE1 for each 1.0 ng/ml increase in PSA (p=0.05). For obese AA men only (BMI> or =30 kg/m2), 2-OHE1 increased by 36% for each decade of age (p=0.009). CONCLUSIONS: Estrogen metabolites may be related to PSA level in AA men. Older men with BMIs greater than 30 kg/m2 had an unexpected increase in 2-OHE1, suggesting a dysregulation of this estrogen metabolism pathway. Further studies of estrogen metabolites may provide insights into prostate cancer risk factors.
