Decontamination of materials contaminated with Bacillus anthracis and Bacillus thuringiensis Al Hakam spores using PES‐Solid, a solid source of peracetic acid

Aims To develop test methods and evaluate survival of Bacillus anthracis Ames, B. anthracis ∆Sterne and B. thuringiensis Al Hakam spores after exposure to PES‐Solid (a solid source of peracetic acid), including PES‐Solid formulations with bacteriostatic surfactants. Methods and Results Spores (≥7 logs) were dried on seven different test materials and treated with three different PES‐Solid formulations (or preneutralized controls) at room temperature for 15 min. There was either no spore survival or less than 1 log (
