Therefore, other than addition of chlorine to chill immersion
tanks and carcass sprayers (a process that becomes
ineffective in the presence of large amounts of organic
material), there is no single decontamination method predominantly
used in commercial poultry processing.
As another example, acidified calcium sulfate (sold by
Mionix Corp., Roseville, CA under the trade name Safe2O)
has been found to be a very effective beef and
poultry carcass washing agent (Huffman, 2002) as well as
a rinsing agent for RTE meats with considerable residual
listericidal or listeristatic activity (Keeton et al., 2002).
According to Mionix, this material disables the proton
pumps in the bacterial membrane and thus attacks bacteria
in a different fashion than other organic acids (e.g.,
lactic). However, only these few studies have been reported.
The potential use of these treatments as part of a
multiple hurdle approach requires further investigations.
