The most important analyte used to verify the cleanliness of a medical device after a cleaning process is protein [1, 2]. There are a variety of different Assays to test for protein, the most commonly used Assays are based on ortho-phthalaldehyde (OPA) and bicinchoninic acid (BCA) [2]. In this study 42 different cleaning detergents from 14 different manufacturers were tested for their potential to influence the output of these Assays.
The members of the Institute of Decontamination Sciences (IDSc) held their annual conference as usual in early December, but on this occasion at a new venue in Hinckley, Leicestershire.
The start to the new year was kicked off with an unpleasant surprise. A novel coronavirus, known as 2019-nCoV, is spreading very rapidly. So far, it has affected mainly people in the Hubei province of China. A few days ago the World Health Organization (WHO) declared this outbreak to be a Public Health Emergency of International Concern (PHEIC). That sounds alarming. The hygiene measures taken to control the outbreak are accordingly radical. What does this virus really mean?
Steam sterilisation conditions are not unambiguously quantified in the literature and standards. In practical situations, it would be helpful if a set of criteria to assess the actual surface steam sterilisation conditions would be available.
A review of the literature and standards is performed. Results from this review, combined with basic physical calculations, are used to determine numerically quantified steam sterilisation conditions.
