You will want to apply the field directly to conductive plates which are

the voltage drop will essentially be all across the air gap, none across
the test sample.
I've been thinking about this. There is a question on how to get an
e-field into the meat, and there is a question about whether bacteria
exist in the meat.
I am assuming there is bacteria in the meat, but I've searched all kind
of FDA and safety sites, and I don't see anything discussed except
ground meat, so I don't know. Maybe there is not, just bacteria on the
surface.
As to whether you can get an efield into the meat, I found that the
authors of the paper actually made a "helmet" to kill brain tumors in
living patients:

They use insulated electrodes (dozens of them, apparently), but you do
have to shave your head so they are close to the scalp. Are they really
driving 1V/cm into someones brain without cooking it? Or is the actual
field required to kill bacteria (and cancer) actually much smaller than
1V/cm? If the voltage is low, why don't they just put the electrodes in
contact with the skalp?
I have not idea if the trial is working, but if the device is curing
patients, then whatever this box does would kill the bacteria in the
meat (whether its there or not) without cooking the meat. I'm assuming
they have fancy DSP to control all of the electrodes, but they still
have to obey the laws of physics.... I think the field intensity to do
this job may be WAAAAAY less than 1V/cm.
