peracetic acid -vinegar and hydrogen peroxide?

I was fishing for a supposedly non toxic way of disinfecting pots and
pans and saw an article about someone using vinegar and hydrogen
peroxide in two spray bottle to disinfect vegetibles. I then read that
this mixture forms peracetic acid. Is it safe to use this mixture?

"4. The effect of the substance on human health.
Peracetic acid is an irritant of the skin, eyes, mucous membranes, and
respiratory tract (NTP, 2000;
Budavari, 1996; Lenga, 1985). When heated to decomposition, it emits acrid
smoke and toxic fumes of
carbon monoxide and carbon dioxide. The vapor is heavier than air and can
travel a considerable distance
to a source of ignition and flash back (NTP, 2000).
While it is not rated as a carcinogen by itself (NTP, 2000), studies
indicate that it is a possible cocarcinogen,
promoting tumor production by known carcinogens (Bock, Myers, and Fox,
1976, from
abstract)."

It is effective and dangerous.

Concentrated peracetic acid is really tricky stuff. About 25 years ago
it was shipped in metal cans. At my alma mater a weirdo ordered 10
liters of the stuff and used less than one. The jerry can was stored
in a fridge for about 10 years. The lid started corroding and rust is
a catalyst for peroxides in general to dissociate... dissociate fast.
Nobody used the fridge anymore. It was forgotten til it broke and was
opened again. A few suicidal fellows wrapped the can in ice and very
carefully put it in a working fridge.
A few years later the explosives specialists from the fire dep.
brought the can out into a field and shot at it. I can still hear the
bang. Very very very nasty stuff.

But... if you mix it yourself with commercially available vinegar (ca.
5%) and peroxide (ca. 3%) none of the previous will be relevant. There
will be a bit of the peracetic acid very diluted in water/acetic
acid/peroxide, but as long as you have decent ventilation and don't
let it get on your skin or breathe it, it should not be a problem. And
after a few hours it will be "dead" anyway.

peracetic acid is manufactured using concentrated peroxide and glacial
acetic acid. They are mixed together and allowed to react for weeks to
achieve a high concentration. mixing dilute 3% peroxide with acetic acid
will not make any appreciable amount of peracetic.

You might as well simply use straight peroxide because all your doing is
making your peroxide

I didn't mix the two together. I simply used 2 spray bottles to spray
vinegar and peroxide on and left a fine mist on vegables and pots and
pans and things like that. I rinsed it off.
peroxide on

The information is very interesting. Now I'm interested in the properties of vinegar.

Joe123 is correct - there is minimal risk from using spray bottles in the way you describe (except perhaps leaving residual peroxide on food if not rinsed carefully)
