Guest guest Posted August 18, 2006 Report Posted August 18, 2006 If you search for " deactivation of trichothecenes " , this article is one of the most frequently cited sources: http://www.nbc-med.org/SiteContent/HomePage/WhatsNew/MedAspects/Ch-34electrv699.\ pdf#search=%22Mycotoxins%2C%20by-products%20of%20fungal%20metabolism%22 It is claimed that sodium hypochlorite " is an effective inactivation agent for trichothecenes " . ---------------------------------------- Moreover, these mycotoxins are not inactivated by autoclaving but require heating at 900°F for 10 minutes or 500°F for 30 minutes for complete inactivation. A 3% to 5% solution of sodium hypochlorite is an effective inactivation agent for them. The efficacy of this solution can be increased by the addition of small amounts of alkali. ------------------------------------------ I have several clothing items made of synthetic materials (sportswear). They were contaminated with something that I suppose can be nothing else but trichothecenes. Details are in this message: /message/41067?var=1 & l=1 I left those clothes in a bucket filled with diluted bleach and some borax for weeks now...adding new bleach and water as the old ones evaporate. But it does not deactivate the offending agent. Whatever it is, it's still attached to them. What's more, they are still very much capable of cross-contaminating other stuff. So, is this information about hypochlorite inaccurate? Has anyone had synthetic material contaminated with trichothecenes that couldn't be decontaiminated with bleach? Does anyone have any idea what I might try in order to deactivate this toxin? I can't be 100% sure it's mycotoxin, but what else can it be? Please let's not get into semantic details... I really need help, not nitpicking about terms. Quote
