Consumer knowledge of foodborne microbial hazards and food-handling practices.

A national telephone survey was conducted of 1,620 randomly selected U.S. residents who spoke English, were at least 18 years old, and resided in households with kitchen facilities. Respondents were interviewed about their recognition of foodborne pathogens, foods at risk for transmitting infection, knowledge of safe food handling, and food-handling practices. One-third of the respondents who prepared meals reported unsafe food hygiene practices: e.g., they did not wash hands or take precautions to prevent cross-contamination from raw meat. Unsafe practices were reported more often by men, adults 18 to 29 years of age, and occasional food preparers than by women, persons 30 years old or older, and frequent food preparers. Respondents who identified a food vehicle for Salmonella spp. were more likely to report washing their hands and cleaning cutting boards after preparing raw meat and poultry. The results raise concerns about consumer food-handling practices. The influence of food safety training, food-handling experience, and age on food-handling practices should be studied further. Awareness of a food vehicle for Salmonella spp., for example, may indicate knowledge of the etiology of foodborne disease that promotes safe food handling. Understanding the factors associated with safe food handling will assist in development of effective safe-food instruction programs.

Associations between diet and health behavior: results from the 1992 Rhode Island Behavioral Risk Factor Survey.

The 1992 Rhode Island Behavioral Risk Factor Surveillance System was used to assess self-reported health behaviors of consumers of finfish and raw shellfish. We hypothesized that consumers of finfish, foods considered to be healthy, were more likely than nonconsumers of finfish to partake in health-promoting behaviors. Similarly, we postulated that consumers of raw molluscan shellfish, foods linked to an elevated risk of acquiring various illnesses, were more likely than nonconsumers of raw-shellfish to partake in risk-taking behaviors. Finfish eaters were significantly more likely than abstainers to report recent exercise, efforts to lose weight, periodic monitoring of serum cholesterol, and not currently being smokers. Raw shellfish eaters were significantly more likely than abstainers to report recent acute and chronic alcohol consumption. The results suggest that inquiry into dietary patterns may be an avenue for exploring other health behaviors.

Hair dye use and risk of fatal cancers in U.S. women.

BACKGROUND: Permanent hair dyes are used by about one third of adult American women. Several epidemiologic studies associate hair dye use with increased risk of non-Hodgkin's lymphoma and multiple myeloma. In one study, risk increased with more prolonged exposure to darker, more concentrated, permanent dyes. PURPOSE: The purpose of our study was to examine the relationship between hair dye use and development of certain cancers associated with hair dye use in previous studies. METHODS: We examined prospectively the relationship between the use of permanent hair dyes and selected fatal cancers in 573,369 women. The participants provided information in 1982 on the frequency and duration of hair dye use and the color of hair dye used. Death rates were measured through 1989. Relative risks (RRs) were computed with subjects who had not used hair dyes serving as the referent group, and 95% confidence intervals (CIs) were calculated on the basis of approximate-variance formulas. RESULTS: Women who had ever used permanent hair dyes showed decreased risk of all fatal cancers combined (RR = 0.93; 95% CI = 0.89-0.98) and of urinary system cancers (RR = 0.65; 95% CI = 0.49-0.87) and no increase in risk of any type of hematopoietic cancer. Women who had used black hair dyes for 20 years (0.6% of women hair dyers) or more had increased risk of fatal non-Hodgkin's lymphoma (RR = 4.37; 95% CI = 1.3-15.2) and multiple myeloma (RR = 4.39; 95% CI = 1.1-18.3). These positive findings are based on three cases of non-Hodgkin's lymphoma and two cases of multiple myeloma. We found no relationship between use of permanent hair dyes and fatal cancers of the mouth, breast, lung, bladder, or cervix, areas that were of interest as the result of earlier studies. CONCLUSIONS: Women using permanent hair dyes are not generally at increased risk of fatal cancer. Women with prolonged use of dark, particularly black, hair dyes may have increased risk of fatal non-Hodgkin's lymphoma and multiple myeloma, but these women are a small fraction of hair dye users. Nonetheless, the removal of carcinogens from hair dyes and appropriate labeling of hair-coloring products would help reduce this potential risk.

Pathogenic and fecal Escherichia coil strains from turkeys in a commercial operation.

The biochemical phenotypes and antimicrobial susceptibility patterns of 105 clinical Escherichia coli isolates from flocks with colibacillosis in a turkey operation were compared with 1104 fecal E. coli isolates from 20 flocks in that operation. Clinical isolates and 194 fecal isolates with biochemical phenotypes or minimum inhibitory concentrations for gentamicin and sulfamethoxazole similar to clinical isolates were tested for somatic antigens and the potential virulence genes hylE, iss, tsh, and K1. The predominant biochemical phenotype of clinical isolates contained 21 isolates including 14 isolates belonging to serogroup 078 with barely detectable beta-D-glucuronidase activity. Thirty-five fecal isolates had biochemical phenotypes matching common phenotypes of clinical isolates. Sixty-six (63%) clinical isolates exhibited intermediate susceptibility or resistance to gentamicin and sulfamethoxazole compared with 265 (24%) fecal isolates (P < 0.001). Seventy-seven clinical isolates reacted with O-antisera, of which 51 (66%) belonged to the following serogroups: O1, O2, O8, O25, O78, O114, and O119. In comparison, 8 of 35 (23%) fecal isolates subtyped on the basis of biochemical phenotype belonged to these serogroups and four of 167 (2%) fecal isolates subtyped on the basis of their antimicrobial resistance patterns belonged to these serogroups. Iss, K1, and tsh genes were detected more often among clinical isolates than these fecal isolates (P < 0.05). In summary, a small subgroup of E. coli strains caused most colibacillosis infections in this operation. These strains existed at low concentration in normal fecal flora of healthy turkeys in intensively raised flocks. The data suggest that colibacillosis in turkey operations may be due to endogenous infections caused by specialized pathogens.

Emerging foodborne diseases.

The epidemiology of foodborne diseases is rapidly changing. Recently described pathogens, such as Escherichia coli O157:H7 and the epidemic strain of Salmonella serotype Typhimurium Definitive Type 104 (which is resistant to at least five antimicrobial drugs), have become important public health problems. Well-recognized pathogens, such as Salmonella serotype Enteritidis, have increased in prevalence or become associated with new vehicles. Emergence in foodborne diseases is driven by the same forces as emergence in other infectious diseases: changes in demographic characteristics, human behavior, industry, and technology; the shift toward a global economy; microbial adaptation; and the breakdown in the public health infrastructure. Addressing emerging foodborne diseases will require more sensitive and rapid surveillance, enhanced methods of laboratory identification and subtyping, and effective prevention and control.

Campylobacter jejuni--an emerging foodborne pathogen.

Campylobacter jejuni is the most commonly reported bacterial cause of foodborne infection in the United States. Adding to the human and economic costs are chronic sequelae associated with C. jejuni infection--Guillian-Barré syndrome and reactive arthritis. In addition, an increasing proportion of human infections caused by C. jejuni are resistant to antimicrobial therapy. Mishandling of raw poultry and consumption of undercooked poultry are the major risk factors for human campylobacteriosis. Efforts to prevent human illness are needed throughout each link in the food chain.

Raw shellfish consumption in California: the 1992 California Behavioral Risk Factor Survey.

We used the 1992 California Behavioral Risk Factor Surveillance System to study the prevalence of raw shellfish consumption in California and the demographic and behavioral characteristics of raw shellfish consumers. We used the logistic regression analysis of the weighted survey data with PC SAS and SUDAAN to adjust for the effects of age and gender. Twenty-three percent of the respondents in the survey reported that they ate raw shellfish; one third of these reported eating raw shellfish once a month. Higher prevalences of raw shellfish consumption were reported by men, persons 18-49 years old, those with income above $25,000 and education beyond high school than by women, individuals older than 49 years, and those with an income of $25,000 or less per year and 12 or fewer years of school. A higher percentage of persons with liver disease, stomach surgery, and a history of chronic alcohol drinking reported consumption of raw shellfish than did individuals without liver disease, previous stomach surgery, or a history of alcohol abuse. After adjustment for gender and age, those who reported acute (P < .01) and chronic (P < .01) drinking and driving while intoxicated (P < .01) were more likely to report consumption of raw shellfish. Two variables (lack of seat belt usage [P = 2] and cigarette smoking [P = .13]) were not significantly associated statistically with raw shellfish consumption.
