Credence: An effective surface disinfectant offering protection against viruses, including Coronavirus
in accordance with EN14476:2013+A1:2015.
What is Credence?
Credence consists of troclosene (sodium dichloroisocyanurate, known as NaDCC). Credence is a broad spectrum, fast acting sanitiser and water steriliser and is effective against bacteria, viruses, fungi and protozoa (Sen, 2016). NaDCC is a stabilised form of chlorine and is quick to act on contaminants. In general terms, a “fast kill rate” is deemed to be less than 15 minutes. Credence displays efficacy against enveloped viruses, such as ASF, within 5 minutes or less which is far quicker than some other disinfectants.
Credence has long persistency in water and is highly cost effective, making it ideal for use in biosecurity programmes. It is also less toxic and corrosive when compared to other available disinfectants. The form of chlorine within Credence is highly stable and therefore very different to other disinfectants commonly used on farm, at home and in veterinary surgeries. As a result of this, when in solution, it has a low volatility and therefore emits minimal odour.
Ideal for use as a surface disinfectant in preventing the spread of bacteria and viruses, the efficacy of Credence against Coronavirus, the virus responsible for the current global pandemic of respiratory illness, has been recognised. Medentech has determined, following the undertaking of a quantitative suspension test to evaluate the virucidal activity of chemical disinfectants, that when used under clean conditions at a concentration of 500 ppm available chlorine, Credence can be used in infection prevention measures against Coronavirus.
Preventing the Spread of Viruses
Viruses can be split into two distinct categories; enveloped or non-enveloped. Enveloped viruses include Avian Influenza, African Swine Fever (ASF) and Coronavirus (Covid-19). Prevention is always more effective than a cure when considering these types of viruses which can have a detrimental impact to animal health and performance. This is particularly true for viruses such as ASF, which has no vaccination or known cure and, in a vast majority of cases, all infected animals will die. ASF is notifiable by law to relevant authorities in most countries and can easily spread from infected pigs and wild boars to equipment and feed materials.
Regular cleaning and a high level of biosecurity are the only ways to ensure a virus does not infect the entire farm or production unit. Boot, wheel and lorry washing is advised, as well as effective drying of equipment following disinfection to ensure that no live virus is transported onto the site. Cleaning animal areas and ensuring the highest possible feed and water hygiene is a fundamental control measure in preventing the spread of viruses within the environment and between animals.
