The scrubbing time of Quorum Pink II HF detergent, a mixture of
sodium metasilicate, tetrapotassium pyrophosphate, sodium linear
alkyl benzene sulfonate, dipropylene glycol methyl ether and
dipropylene glycol n-propyl ether, had little effect on E. coli and
enterococci reduction. This is a slight surprise since, although it
is only a detergent with no disinfection ability at this concentration,
and thus is not expected to reduce the viability of either bacterial
group, it is, however, a good surfactant and so is expected to
remove hydrophobic food residues and bacterial extracellular
polysaccharides and, therefore, reduce both their proliferation
and adhesion, respectively. In any case, Quorum Pink II HF was
accepted by Thailand DLD to be used in animal slaughterhouses
and meat processing factories and is widely used in the food plant
industry in Thailand
