A semi-quantitative dermal exposure assessment method based on visual observations of fluorescence images was presented by Fenske in 1988. We adapted the method to Nicaraguan working conditions and evaluated its performance. Thirty-two farmers applied chlorpyrifos and methamidophos marked with Tinopal CBS-X(R). Skin fluorescent depositions were observed with a portable UV lamp in a foldaway dar...

Contamination of food producing animals by veterinary drug residues, particularly quinolones, is an essential issue in food safety that causes increasing concern in consumers. The aim of this study was to investigate the occurrence of enrofloxacin and its main metabolite, ciprofloxacin, in chicken tissue samples slaughtered in Tabriz, Iran. Totally 250 samples including liver, muscle, gizzard, ...

Broiler meat can become contaminated with Campylobacter of intestinal origin during processing. The present study aimed to identify the prevalence of Campylobacter in broiler flocks and meat contamination at retail shops, and determine the influence of semi-automated and wet market processing on Campylobacter contamination of neck skin samples. Samples were collected from semi-automated plants ...

Sir, The frequent dermatophyte infections of swimmer’s feet are most likely related to increased exposure to dermatophytes and maceration of skin (1). Fungal particles are shed from infected tissues and found on the floors of shared bathing facilities (2–5). Two studies have revealed a higher level of contamination in men’s dressing rooms than in women’s (2, 4), and a higher rate of tinea pedis...

The primary objective of premilking udder preparation and teats antiseptic is to achieve an acceptable level of decontamination of teat skin. This aids in reducing the spread of microorganisms and incidence of new intramammary infections, and in minimising the number of bacteria. The aim of our studies was to investigate the influence of pre-milking teat antiseptic solutions on total bacterial ...

Contamination of blood cultures is believed to occur mainly during the venepuncture procedure. Consequently, meticulous preparation of the venepuncture site is widely recommended. To determine whether the contamination rate is indeed affected by the quality of the antiseptic procedure at the venepuncture site, 181 paired cultures were collected from 176 patients during a 6-month period after ei...

UNLABELLED Ultrasound examinations are recognised as being safe. The greatest epidemiological threat during the performance of examination is the transfer of pathogenic and opportunistic microorganisms between patients and from personnel to patients. Colonization of the skin with opportunistic bacteria of immunocompromised and high risk patients may lead to infection following an ultrasound sca...
