Description
METHOD FOR APPLYING BACTERICIDAL SOLUTIONS
TECHNICAL FIELD
This invention relates to a method for applying bactericidal solutions in the
bactericidal treatment of contaminated produce, apparatus and surfaces.
BACKGROUND ART
The application of bactericidal solutions in the bactericidal treatment of
contaminated produce, equipment and surfaces is usually carried out by
means of washing, with solutions such as chlorine solutions, etc. or by
means of steaming. However, total wetting during washing and/or high
temperatures during steaming are often disadvantageous in that they are
unacceptable and even detrimental to the produce, apparatus and/or
surfaces.
For purposes of this application the term "medium" shall include produce,
apparatus and surfaces and cognate terms shall have similar meanings.
OBJECTIVES OF THE INVENTION
It is accordingly an object of this invention to produce a method and
equipment for applying bactericidal solutions that will overcome the above
disadvantages.
DISCLOSURE OF INVENTION
According to a first aspect of the invention there is provided a method for
applying electrochemically activated, bactericidal solution to a
contaminated medium to be treated, including the step of atomising and
dispersing the solution into the atmosphere about a contaminated medium
to be treated, forming a fog of airborne droplets of between 1 and 100
micrometers of suitable bactericidal concentration about the treated
medium.
The electrochemically activated, bactericidal aqueous solution may be
selected from a group consisting of anion-containing and cation-containing
solutions.
The electrochemically activated, bactericidal aqueous solution may be
prepared by means of electrolysis of an aqueous solution of a salt. The
salt may be sodium chloride. In particular, it may be non-iodated sodium
chloride or potassium chloride.
The anion-containing solution and the associated cation-containing solution
may be produced by an electrochemical reactor or so-called electrolysis
device having a through flow electrochemical cell with two co-axial
cylindrical electrodes, with a co-axial diaphragm between the two
electrodes so as to separate an annular inter-electrode space into a
catalytic and an analytic chamber. The anion-containing solution is referred
to hereinafter for brevity as the "anolyte solution" or "anolyte" and the
cation-containing solution is referred to hereinafter for brevity as the
catholyte solution" or "catholγte".
The anolyte solution may be produced from an about 3 to 1 0% aqueous
NaCl solution, electrolysed to produce mixed reductant and mixed oxidant
species. These mixed reductant and oxidant species may be labile and
after about 96 hours the various oxidant and reductant species may
disappear with relatively no residues being produced. The anolyte solution
may have a suitable redox potential, preferably of about between + 450
mV and + 1 200 mV and may have a suitable pH, preferably of between 2
and 9 for bactericidal treatment of a specific medium. The anolyte solution
may include mixed oxidant species such as CIO; CIO ; HclO; OH ; HO2 " ;
H2O2; O3; S2O8 2" and CI2O6 2\
The catholyte solution may have a suitable pH, preferably of between
about 1 2 and 1 3, and a suitable redox potential, preferably of between
about -200 mV and -900 mV, for bactericidal treatment of a specific
medium. The catholyte solution may include reductant species such as
OH"; H3 "; 02; H2-; H02 ; H02 " and 02 ".
The method may include the preliminary step of enclosing the contaminated
medium to be treated in a closed volume prior to atomising and dispersing
the solution into the closed volume.
The atomising and dispersing step is preferably repeated at pre-determined
intervals so as to maintain a suitable fog concentration in the closed
volume, thus utilising the microcidal and other properties of the
electrochemically activated solution without detrimentally affecting the
quality and condition of the produce, such as reducing dehydration and
weight loss, the equipment and/or the surfaces to be treated.
According to a second aspect of the invention there is provided equipment
for use in a method for applying electrochemically activated, bactericidal
aqueous solution as hereinbefore defined, the equipment including an
electrolysis device having a through flow electrochemical cell with two co¬
axial cylindrical electrodes, with a co-axial diaphragm between the two
electrodes so as to separate an annular inter-electrode space into a
catalytic and an analytic chamber; and means for atomising and dispersing
the solution into the atmosphere about a contaminated medium to be
treated.
BEST MODE FOR CARRYING OUT THE INVENTION
A preferred embodiment of the invention will now be described by means
of non-limiting examples only.
Example 1 :
Multiple fogging cycles were used so as to determine the efficacy thereof
on the total bacterial surface loads in a series of chillers over a 42 hour
chilling period.
Samples 1 , 2 and 3 were carcasses fogged separately in closed chillers
with 30 minute intervals. Samples 4 and 5 were carcasses sampled in
operating chillers. Foggers were put on the floor of the chillers and
carcasses were therefore not fogged directly. 3 x sampling was conducted
42 hours after the previous fogging on all samples so as to establish
whether there would be an increase in bacterial loads over the 42 hours
prior to de-boning.
Multiple fogging in areas where the fog is not mechanically removed from
the room during the fogging process is highly effective in reducing total
counts.
Fogging in operating chillers is not effective.
Throughout the trial Coliform counts were low, most probably due to
carcass washing and results therefore were not given. The results are
shown in the accompanying tables.
Example 2 :
Enclosed volumes containing diverse equipment, including 2 tables and a
scale, were fogged so as to determine the microcidal effect of anolyte on
the enclosure surfaces and the enclosed equipment.
The results are shown in the accompanying tables.
Example 3 :
Cattle carcasses were treated at the Agricultural Research Council Unit,
Irene, Gauteng, South Africa.
The anolyte used was generated under and with the following
characteristics :
Current : 10 Ampere; Voltage : 24 Volt
ORP : + 762 mV; TDS; 6,04 g/£
pH : 6,8
The chiller treated had volume (space) for about 1 6 carcasses. The
fogging process consisted of 3 cycles of 20 minutes each, with 10 minutes
in between each cycle.
Samples were taken from the neck area, the breast area, the back area and
the hindquarter area.
Samples were taken of all micro-organisms by means of total plate count
( Redoc plates), total plate counts (petri film) and Coliforms (petri film).
The results are shown in the accompanying tables.
Example 4 :
A number of 800 lamb carcasses were subjected to tests, 400 being
fogged with anolyte and 400 being used as the control group. Samples
were taken before treatment, after a second cycle and a fourth cycle, while
the control group was sampled before and after 24 hours of chilling.
Additional samples were taken from both the treated and the control group
for measuring TPC only.
The results are shown in the accompanying tables.
It will be appreciated that many variations in detail are possible without
departing from the scope and/or spirit of the invention as claimed in the
claims hereinafter.
Example 1: (New Style Pork)
Objective:
To determine the effect of multiple fogging on the total bacterial -surface loads over a 42 hour chilling period.
Comments
1, 2 and 3 were fogged separately in chillers with 30 minutes intervals.
Chillers were not in operation. After fogging, carcasses were returned to original chillers.
Example 2 :
Microcidal Effect of Anolyte on Surfaces and Equipment
Example 3: (Calf Carcasses) A. Trial Carcasses Direct fogging in chiller with interrupted air circulation during the fogging process
Comments:
The fourth Swab was on the side of the triceps cut where all carcasses had been pushed by hand and were therefore more contaminated than adjoining surfaces.
All swabs were incubated at 37° C for 48 hours Coliform counts were negligible on all carcasses
B. Negative Control : Indirect fogging of carcasses that were present in the chiller, during the time of the experiment. Only final carcass counts on similar locations as the trials were taken.
Example 4:
Woolworths Trial 800 lamb carcasses
Results:
Treatment with Anolvte
Control group:
Further swabs were taken on the shoulder of 5 chilled and fogged carcases (after the 4th fogging).
