Abstract Use of Acid Water to Clean Plastic Cutting Boards One milliliter of culture containing a five-strain mixture of Escherichia coli O157:H7 (approximately 10(10) CFU) was inoculated on a 100-cm2 area marked on unscarred cutting boards. Following inoculation, the boards were air-dried …
Abstract Objective To determine the bactericidal effect on surfaces of ceiling‐ and wall‐mounted UV C (UVC) light (wavelength, 254 nm) in isolation units, compared with standard hospital environmental cleaning and chemical disinfection during final disinfection after patients are treated for infections. Design …
Escherichia coli (abbreviated as E. coli) are a large and diverse group of bacteria. Although most strains of E. coli are harmless, others can make you sick. Some kinds of E. coli can cause diarrhea, while others cause urinary tract infections, respiratory illness and pneumonia, …
Abstract Assessment of the risks posed by severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) on surfaces requires data on survival of this virus on environmental surfaces and on how survival is affected by environmental variables, such as air temperature (AT) and relative humidity (RH). …
The swabs used for sampling surfaces for microbial contamination are examples of devices that are simple in design and construction, but are difficult to use without discipline and training. This article discusses why this is so. At present, swabs are widely used in the cleaning …
H.S.Olsen; P. Falholt. “The Role of Enzymes in Modern Detergency” J. Surf. Det., 1(44), 555-567 (1998) Abstract Enzymes have effectively assisted the development and improvement of modern household and industrial detergents. The major classes of detergent enzymes – proteases, lipases, amylases and …
Comparison of results of ATP bioluminescence and traditional hygiene swabbing methods for the determination of surface cleanliness at a hospital kitchen. Abstract Adenosine triphosphate (ATP) bioluminescence and traditional microbiological swabbing culture methods were used for detection of surface hygiene on worktops, cutting boards …
Abstract Dishcloths used in restaurants and bars (23 restaurant cloths, 14 bar cloths) were collected, and tabletops (10 restaurants) were swabbed, to determine the occurrence of bacteria. Coliforms were isolated from 89.2% of dishcloths and 70% of tabletops. Escherichia coli was isolated from 54.1% …
Abstract: A four-part study assessing cleanliness in up to 113 environmental surfaces in an operating theater and a hospital ward was reported. Surfaces were assessed visually, using microbiological methods and ATP bioluminescence. Results from a preliminary random survey indicated variability in cleanliness. These results …
Some 40% of commercial disinfectants used to clean surfaces are believed to be ineffective in eliminating noroviruses, a group of viruses responsible for more than half of all foodborne gastroenteritis outbreaks. According to a recent study published by Université Laval researchers in the Journal of …
