purpose: to evaluate bacterial and fungal contamination of donor corneas before and after decontamination at eye bank of i.r. of iran based on cultures. methods: this descriptive study was performed on 131 donor eyes (whole globe or cut cornea) used for corneal transplantation at labbafinejad hospital during a 6-month period. microbiologic culture was performed at three stages: before enucleati...

BACKGROUND PCR amplification of minute quantities of degraded DNA for ancient DNA research, forensic analyses, wildlife studies and ultrasensitive diagnostics is often hampered by contamination problems. The extent of these problems is inversely related to DNA concentration and target fragment size and concern (i) sample contamination, (ii) laboratory surface contamination, (iii) carry-over con...

In Europe, on-farm biosecurity measures, involving a strict all-in/all-out batch-management system and decontamination of the rearing rooms between consecutive batches, are recommended to control Salmonella infection in growing pigs. However, implementation of these measures is often relaxed under common farming conditions. Therefore, this study was conducted to assess the relative contribution...

Eggs have a high nutritional value and are an important ingredient in many food products. Worldwide foodborne illnesses, such as salmonellosis linked to the consumption of eggs and raw egg products, are a major public health concern. This review focuses on previous studies that have investigated the procedures for the production of microbiologically safe eggs. Studies exploring pasteurization a...

This short report presents a response to an article written by Cibulsky et al. (2016). The paper by Cibulsky et al. presents a useful and timely overview of the evidence surrounding the technical and operational aspects of mass casualty decontamination. It identifies three priority targets for future research, the third of which is how casualties' needs can be met in ways that best support comp...

The paper investigates to what extent context dependency is present, when consumers are introduced to different risk reducing technologies and how this will affect their preferences for reductions in food risks. In particular, choice experiments are used to elicit consumer preferences for reducing Salmonella risks in pork using farm level interventions vs. decontamination of meat at the abattoi...

The efficiency and speed with which first responders, paramedics, and emergency physicians respond to an event caused by the release of a chemical is an important concern in all modern cities worldwide. A system for the initial triage and decontamination of victims of a chemical release was developed using colored clothes pegs of the following seven colors: red, yellow, green, black, white, and...

The efficacy of ultraviolet C (UVC) light (100-280 nm) in the decontamination of three hospital-related surfaces, namely, unpainted/painted aluminum (bed railings), stainless steel (operating tables), and scrubs (laboratory coats), was investigated. Acinetobacter baumannii cells were inoculated (10(5) or 10(3) cells) on small coupons and dried overnight in a class II biosafety cabinet. Drying r...

The National Laboratory Certification Program undertook an evaluation of the dynamics of external contamination of hair with cocaine (COC) while developing performance testing materials for Federal Drug-Free Workplace Programs. This characterization was necessary to develop performance materials that could evaluate the efficacy of hair testing industry's decontamination procedures. Hair locks (...

BACKGROUND Despite standard manual decontamination, hospital equipment remains contaminated with microorganisms, contributing to nosocomial transmission and hospital acquired infections. This has the potential to negate the effects of healthcare workers' hand-washing protocols. In order to decrease the likelihood of equipment contamination, there has been a rise in the use of disposable pieces ...
