[USCC] O157 E Coli

Sun Dec 17 23:49:50 CST 2006

The 503 regulations requireing 55oC are very effective at destroying O157. Literature shows that the D values (decimal reduction times) is between 36 and 3 hours. This is more effective than D values for Salmonella. Furthermore there is evidence that indigenous organisms hasten the destruction of O157. Obviously one needs to avoid recontamination.

Again I urge as many of you to attend the Council meeting in Orlando and support our organization. If you are not a member become one so that we can continue to serve yoy.
