anitisers/Disinfectants: (These products must be
used as advised by the manufacturer).
90% inactivation was produced by sodium
hypochlorite at a concentration 0.5-1.5 mg/litre free
chlorine and at 4
o
C. A 6D reduction was achieved on
inoculated parsley with 5.2% acetic acid or 200 ppm
free chlorine after 5 minutes exposure at 21
o
C.
Treatment with 7.6% acetic acid or 250 ppm chlorine
increased the kill to >7D.
(N.B. The absence of a sanitiser/disinfectant from
this section does not necessarily imply that it is
ineffective).
