A study of six child care centers was conducted to assess the microbiological quality of three food contact surfaces (one food serving surface and two food preparation surfaces) and one non-food contact surface (diaper changing surface) to determine the effectiveness of cleaning and sanitization procedures within the facilities. Aerobic plate counts (APCs) and Escherichia coli/coliform counts o...

Background: Food borne illnesses and food poisoning are cause for concern globally. The diseases are often caused by food contamination with pathogenic bacteria due largely to poor sanitary habits or storage conditions. Objectives: Prevalence of some bacteria on cleaned and sanitised food contact surfaces from eight convenience food plants in Gauteng (South Africa) was investigated with the vie...

AIMS   To test the efficacy of four wipe cloth types (cotton bar towel, nonwoven, microfibre and blended cellulose/cotton) with either quaternary ammonia cleaning solution or silver dihydrogen citrate (SDC) in cleaning food contact surfaces. METHODS   Swab samples collected from untreated, cloth-treated and cloth disinfectant-treated surfaces were subjected to hygiene monitoring using adenosi...

Trachoo, N. Biofilms and the food industry Songklanakarin J. Sci. Technol., 2003, 25(6) : 807-815 In the past, interest in biofilms was limited to research related to water distribution systems, waste water treatment and dental plaques. Biofilm has become a more popular research topic in many other areas in recent years including food safety. Biofilm formation can compromise the sanitation of f...

Pathogens and spoiling microorganisms which adhere to interior equipment surfaces may be transferred to food products during their processing. To improve the hygiene during food processing operations, either inorganic or organic antimicrobials are added to various materials of construction used in the manufacturing of food processing equipment. In the USA, antimicrobials used in materials of co...

in this paper, the dynamics of evaporation of water droplets on surfaces with different contact angle hysteresis is studied experimentally and theoretically. the evaporation of water droplets on surfaces usually occurs in three distinct stages, namely the constant contact area mode, followed by the constant contact angle mode, and the mixed mode in which both contact angle and contact area are ...

Food allergies affect an estimated 10 to 12 million people in the United States. Some of these individuals can develop life-threatening allergic reactions when exposed to allergenic proteins. At present, the only successful method to manage food allergies is to avoid foods containing allergens. Consumers with food allergies rely on food labels to disclose the presence of allergenic ingredients....

The consumption of street food is an economical and practical alternative for the population. However, concerns regarding the safety of these foods are increasing.
