“…It was reported that large doses (10 5 -10 7 CFU) of enteropathogenic organisms and 10 6 CFU of S. aureus are required to cause an infection. 3 In our study, isolated bacteria counts were between 21-563 CFU, in the range of previously reported results above; and therefore, the risk of infection is unavoidable.…”

“…Several types of disinfectants have been previously and recently recognized as more effective antimicrobial tools over boiling, soap and water washing, which are often either ineffective or not feasible. 3 A thorough discussion of disinfection and hand washing, as antimicrobial tools, is made in introduction section. In parallel with decontamination tools, community awareness and education for hygienic standards, respiratory etiquette and hand-washing should be taken seriously into consideration.…”

“…1,2 Recent epidemiological studies have reported fomites in the transmission of human pathogens within high-exposure environments such as hospitals, child-care facilities, long-term care facilities, and sports facilities. 3,4 Various types of microorganisms were identified, including rotavirus, rhinovirus, methicillin-resistant Staphylococcus aureus (MRSA), and Serratia marcescens, to cause gastrointestinal diseases, the common cold, necrotizing fasciitis, and catheter associated bacteremia, respectively. 4 Microbial contaminations are widely reported in different indoor and outdoor environments.…”

The occurrence of potential pathogens and the levels of contamination at individual sites, particularly in fitness club, gas station, home, hospital, and supermarket in Kuwait is described in this paper. The samples were collected using sterile swab sticks. Results obtained showed the highest bacterial count of 2.8 log10 CFU/ml in bathroom doorknobs at gas station, while the least was obtained from pantry in hospital with 1.3 log10 CFU/ml. Prevalent isolated bacterial contaminants were Staphylococcus epidermidis (34%), followed by Enterococcus faecalis (26%), Staphylococcus aureus (14%), Escherichia coli (10%), Streptococcus pyogenes and Pseudomonas alcaligenes (4%), Streptococcus agalactiae, Klebsiella oxytoca, Klebsiella pneumoniae, and Pseudomonas aeruginosa (2%). Eighty percent of all swab samples cultured were gram positive and 20% were gram negative bacteria. The types and numbers of diseasecausing microbes reported in previous epidemiological studies were also found in this study. Appropriate hygienic measures to suppress any potential microbial crosscontamination are therefore needed. It is also imperative to conduct regular testing to check for bacterial contamination and increase community awareness and education for hygienic standards.

“…7 A domestic hygiene approach that incorporates disinfection is well recognized as an effective approach to infection control in the developed world. 8 As cleaning with soap and water may cross-contaminate surfaces, disinfection is recommended to reduce prevalence of pathogens on surfaces after illness, and prevent cross-contamination during food preparation. 8,9 The International Scientific Forum on Home Hygiene (ISFHH) promotes surface disinfection as an important intervention for reducing disease transmission risk.…”

Abstract. Surface-mediated disease transmission is understudied in developing countries, particularly in light of the evidence that surface concentrations of fecal bacteria typically exceed concentrations in developed countries by 10-to 100-fold. In this study, we examined fecal indicator bacterial contamination of dinner plates at 21 households in four periurban communities in the Peruvian Amazon. We also used surveys to estimate household use of and demand for surface disinfectants at 280 households. Despite detecting total coliform, enterococci, and Escherichia coli on 86%, 43%, and 24% of plates sampled, respectively, less than one-third of households were regularly using bleach to disinfect surfaces. Among non-users of bleach, only 3.2% of respondents reported a new demand for bleach, defined as a high likelihood of using bleach within the next year. This study highlights the potential for marketing approaches to increase use of and demand for surface disinfectants to improve domestic hygiene.

“…The risk of food-borne infection associated with crosscontamination depends on two factors: the level of contamination on the surfaces and the probability of its transfer to the foods being consumed [49]. The present microbiological survey revealed that there is an urgent need for considerable improvement in the bacteriological quality of products and it should be free from cross-contamination.…”
