US - New information has become available to producers to assist with disinfection protocols for Porcine Epidemic Diarrhoea virus (PEDv).
Disease outbreaks in swine herds are constant threats to the pork industry in the United States. Recently, PEDv has worked its way across different types of swine production, initiating awareness to increase and improve cleaning and disinfection protocols for facilities and transportation vehicles to help limit the spread of PEDv.
New information has become available to producers to assist with disinfection protocols, reports Michigan State University.
Typically a disinfectant becomes neutralised in the presence of organic matter such as swine feces and manure.The National Pork Board recently published a study on the use and effectiveness of Accel (Accelerated Hydrogen Peroxide (AHP)) in cold temperature environments (-10 degrees Fahrenheit).
Although washing, disinfecting and drying the trailer is still the gold standard to greatly reduce the spread of disease, when time is limited to complete a full wash and disinfection process there is another option with the Accel product.
This study was done in situations with with both a heavy and light fecal load and at standing times of 40 and 60 minutes. A summary of those findings are:
PEDv was inactivated in the presence of light and heavy faecal contamination. It was found that concentrations of 1:16 and 1:32 of AHP disinfectant in a 10 per cent propylene glycol solution were effective. Contact times of 40 minutes and 60 minutes were also tested and found that in both cases the virus was inactivated.
It is suggested that when washing, disinfecting and drying the trailer are not possible; using a minimum of a 1:32 concentration of AHP disinfectant in a 10 per cent propylene glycol solution with 40 minutes of contact time is an effective alternative to reduce the risk of PEDv transmission between loads during cold weather conditions. This option gives producers and transporters more flexibility in the disinfection processes for their transport vehicles.
An earlier controlled study performed by a research team at Iowa State University demonstrated that under simulated field conditions (those normally seen in swine trailers) Accel was able to kill 100 per cent of the PEDv in the presence of both light and high (up to 25 per cent) amounts of fecal matter.
Other benefits include the fact that Accel is Hydrogen Peroxide based, therefore does not require the use of PPE (Personal Protection Equipment) when being applied, and is also environmentally friendly. Accel also acts as a cleaner or detergent that reduces the need for pre-cleaning prior to disinfection.
Dr Madonna Benjamin, Michigan State University Extension Swine Veterinarian believes that this product, when used as part of a cleaning biosecurity regime may reduce pathogens on both commercial and non-commercial swine movement. In particular, youth, producers and fair organizers involved in show pigs or 4-H pigs should consider how this product might be used to improve biosecurity in public and commingled forums such as trailering and on the fair grounds.
Accel is patented and manufactured by Virox Technologies Inc. and is available in liquid form and pre-treated hand wipes.
