Electric mixer-inflicted scalp injury: a case report and review of CPSC data.

Electric mixers present a major risk for childhood injuries. Scalp injury, although rarely encountered, results from hair entanglement in the mixer blades. Potential for serious injury and disfigurement exists. The US Consumer Product Safety Commission data indicate that most injuries inflicted by electric mixers are either minor electrical shock or traumatized fingers and hands. Constant observation is mandatory when operating an electric mixer in the presence of children.

Sociodemographic and behavioural correlates of severe dental fluorosis.

OBJECTIVES: The aim of this study was to identify sociodemographic and behavioural factors associated with the prevalence of severe dental fluorosis in moderate- and high-fluoride areas of the Ethiopian Rift Valley. METHODS: Three hundred and six adolescents (12-15 years) and 233 mothers participated in the study. The children were examined for dental fluorosis according to the Thylstrup-Fejerskov Index (TFI). The children and their mothers were subsequently interviewed. Sixty mothers had more than one participating child. In order to perform a paired parent/child analysis, a total of 73 younger siblings had to be excluded. RESULTS: Among the remaining 233 children, the prevalence of severe dental fluorosis (TFI >or= 5) was 24.1% and 75.9% in the moderate- and high-fluoride areas, respectively. According to bivariate as well as multivariate analyses, a number of sociodemographic and behavioural factors were related to severe fluorosis. The odds for having severe fluorosis varied according to the fluoride concentration of the drinking water, age, consumption of tea, length of breastfeeding and method of storing water. The adjusted odds ratios ranged from 2.6 to 26.1. Breastfeeding for > 18 months and the use of clay pots for storing drinking water helped protect against severe dental fluorosis. Bivariate analyses indicated that being male and consuming fish might be associated with higher TFI scores. CONCLUSION: In order to avoid dental fluorosis, low-fluoride drinking water should be provided in the relevant villages. A prolonged period of breastfeeding, the use of clay pots for storing water, and possibly a reduced intake of tea and whole fish in infants might also help to avoid severe fluorosis in children growing up in traditionally fluoride-endemic areas.

Survival of verocytotoxigenic Escherichia coli O157 in soil, water and on surfaces.

Cattle and sheep are major reservoirs of Escherichia coli O157 and consequently these and certain other farm animals can pass out large numbers of this organism in their faeces. Thus the ability of the organism to survive in faeces, on pastureland and in associated water systems has important implications for its spread to crops by direct application of manure, by irrigation with infected water or directly to man by contact with animals or contaminated soil. Model systems were used to determine the persistence of the organism in river water, cattle faeces, soil cores and on stainless steel work surfaces. Survival of the organism was found to be greatest in soil cores containing rooted grass. Under these conditions viable numbers were shown to decline from approximately 10(8) g(-1) soil to between 10(6) and 10(7) g(-1) soil after 130 d. When the organism was inoculated into cattle faeces it remained detectable at high levels for more than 50 d. In contrast the organism survived much less readily in cattle slurry and river water where it fell in numbers from more than 10(6) ml(-1) to undetectable levels in 10 and 27 d, respectively. The survival of E. coli O157 was also investigated on stainless steel surfaces, where as air-dried deposits, it was shown to survive for periods in excess of 60 d. It was most stable at chill temperatures (4 degrees C) and viability was only partially reduced at 18 degrees C. In addition to stainless steel, the organism was shown to survive for extended periods on domestic (plastic) cutting boards, both at room and chill temperatures. Sanitizing agents, such as hypochlorites and a compound comprising both cationic and anionic-based active ingredients were found to be effective in killing various VTEC on stainless steel surfaces.

The effect of an antibacterial washing-up liquid in reducing dishwater aerobic plate counts.

AIMS: To assess any significant differences in the aerobic plate count (APC) of catering dishwaters following the use of a traditional, nonantibacterial or an antibacterial washing-up liquid. METHODS AND RESULTS: A dishwashing trial was undertaken within a commercial restaurant of 6 weeks duration (3 weeks with each washing-up liquid in a randomized, weekly pattern). Five replicate samples were taken from the dishwater at the end of the washing-up operation, on three separate occasions each day corresponding to mid-morning, lunchtime and mid-afternoon meal preparations. CONCLUSIONS: The antibacterial product was shown to significantly reduce the APC by an average log10 reduction of 1.81 CFU ml(-1) (98.5%) as compared with the traditional product. APC were lower for each of the three weekly time periods for the antibacterial product. Continued use of the antibacterial product did not decrease the APC of the dishwater, though with the traditional product, dishwater counts increased throughout the trial week. SIGNIFICANCE AND IMPACT OF THE STUDY: Antibacterial washing-up liquids, with proven activity in controlling levels of microorganisms in dishwaters, could play a significant role in reducing the risk of cross-contamination between washed articles during washing-up operations.

Efficacy of electrolysed oxidizing water in inactivating Vibrio parahaemolyticus on kitchen cutting boards and food contact surfaces.

AIM: To determine the efficacy of electrolysed oxidizing (EO) water in inactivating Vibrio parahaemolyticus on kitchen cutting boards and food contact surfaces. METHODS AND RESULTS: Cutting boards (bamboo, wood and plastic) and food contact surfaces (stainless steel and glazed ceramic tile) were inoculated with V. parahaemolyticus. Viable cells of V. parahaemolyticus were detected on all cutting boards and food contact surfaces after 10 and 30 min, respectively, at room temperatures. Soaking inoculated food contact surfaces and cutting boards in distilled water for 1 and 3 min, respectively, resulted in various reductions of V. parahaemolyticus, but failed to remove the organism completely from surfaces. However, the treatment of EO water [pH 2.7, chlorine 40 ppm, oxidation-reduction potential 1151 mV] for 30, 45, and 60 s, completely inactivated V. parahaemolyticus on stainless steel, ceramic tile, and plastic cutting boards, respectively. CONCLUSIONS: EO water could be used as a disinfecting agent for inactivating V. parahaemolyticus on plastic and wood cutting boards and food contact surfaces. SIGNIFICANCE AND IMPACT OF THE STUDY: Rinsing the food contact surfaces with EO water or soaking cutting boards in EO water for up to 5 min could be a simple strategy to reduce cross-contamination of V. parahaemolyticus during food preparation.
