Virucidal efficacy of nine commercial disinfectants against porcine circovirus type 2

No reduction in PCV2 titre was demonstrated with iodine and phenolic products. Significant PCV2 titre reductions (⩾1.61 log10) were noted for the seven other products. For five disinfectants, namely a product composed of potassium monopersulfate, two products comprising a quaternary ammonium with one or three aldehyde(s), sodium hypochlorite, and sodium hydroxide, the concentration that significantly reduced the PCV2 titre was equal or 1.5-4 times lower than the authorised use concentration. Only two disinfectants, one composed of potassium monopersulfate, the other containing peracetic acid with hydrogen peroxide, reduced the PCV2 titre with a product concentration at best equal or two times higher than the authorised use concentration.
