My apologies..
Previously I said sodium hypochlorite at 10,000ppm. That's fast but probably too corrosive. 5000ppm should be adequate to kill spores with the correct wet contact time.

Subject: [PMFLIST] Bacillus cereus group contamination

Dear Forum,

I would be interested to know how others are handling Bacillus spore contaminations in your facilities? We have been experiencing a persistent contamination occurence of certain Bacillus cereus group bacterium in several locations,   but the origin / root cause is not yet clear. If others have had similar issues, I would appreciate your insight. What kind of sporicides did you use, e.g. Sodium hypochlorite (5000 ppm) or hydrogen peroxide (6 %). What about hydrogen peroxide vapour (6%)?

Kind regards, Joan
