Food
& Other Important Things,

A
Glove on the Hand May Not be Worth a Bar of Soap
If you have noticed,
in more and more over-the-counter food service operations that the person
preparing your food is wearing plastic gloves you have got a glimpse
of a requirement which is blossoming into controversyand genuine
disagreement among professional.
The issue of gloves n the preparation of ready-to-eat foods
began with the increased awareness (as more and more people eat out)
that dirty hands can spread disease. The controversy begins, of course,
with the obvious knowledge that dirty gloved hands can spread disease,
too.
The matter will be immediate in less than a month as the
new, November rules for food service go into effect. At that time the
FDA Food Code is scheduled to become law in this state. It requires
that "suitable utensils" replace the bare hand in contact
with ready to eat food. Suitable utensils can include "deli tissue,
spatulas, tongs, single use gloves or dispensing equipment." Most
used "utensil" is the glove, which may be a loose fitting
polyethylene glove, good for light tasks that require frequent changing,
or a vinyl glove which is tighter (closer fitting) and is good for jobs
that require a better feel for the products. There is a latex glove
also, but there are enough reports of workers developing an allergy
either to the material or to the powder which enables one to get them
on that this glove is not recommended for food handling, essentially
leaving only the two kinds.
In favor of the glove "barrier" to the bacteria
on the bare hand is that they do cover hands which might be unclean.
They make an operation look professional to customers, too, who tend
to think that the glove use is protecting them. It seems like such an
obvious concern for customer welfare. Inspectors and food managers like
them because it is easier to check this kind of "compliance"
than it is to check if the employees have washed hands. And it is easy
for the employee.
But, serious objections exist, also. The main one is that
gloves can, and do, provide a false sense of security; food workers
wearing gloves tend to think that they can do no harm because their
hands are covered and feel secure. There are, however, credible studies
that show that contaminated gloves can transfer pathogens to food and
other surfaces even better than bare hands.
Probably the most damaging objection is that as improper
handwashing is the primary culprit requiring the use of gloves, the
gloves quickly become just another "skin" and one is back
with the handwashing problem againbecause federal requirements
say that the employee must change gloves as jobs change and hands must
be thoroughly washed before putting on the new pair of gloves!
In fact, the skin contamination requiring the use of gloves
is not just a product of "dirty" hands (as after a trip to
the toilet) but acquired from the constant touching of the face, the
nose, the mouth by the employee. There is an interesting video taken
of various kitchens without worker knowledge that show how often, all
of us, touch our faces, especially the mouth area, without realizing
it. It is said that the mouth is the most contaminated orifice in the
body! (Some of the language on TV would seem to indicate the truth of
this.) Another problem develops when the gloves are worn a long time
without changing. The humidity beneath the gloves helps any bacteria
on the hands to grow. However, there are some food preparation operations
(salads for instance) where the wearing of the loose-fitting polyethylene
gloves is very fitting.
Food Talk, a trade publication which is the source for many
of the facts in this piece, reports some interesting information from
a very large food chain in Texas, H-E-B Grocery, which requires its
food service employees to wear gloves on properly washed hands. They
report good results, but a spokesman notes, "Don't put gloves on
dirty hands
without handwashing, gloves are a failure."
There also is a study published in December of 1998 by Dairy
Food and Environmental Sanitation which compared the effectiveness of
handwashing versus glove use in controlling contamination. The research,
which was funded by a hand sanitizer manufacturer, concluded that bare
hands, washed and sanitized hourly, had lower bacterial levels than
gloved hands. In fact, the study found germ levels on gloved hands,
changed hourly with handwashing in between, were almost as high as those
on bare, unwashed hands.
One of the instructions for using gloves "correctly"
requires that one wash hands and change gloves after sneezing, coughing
or touching the face or other body parts with gloved hands. (!) Readers
must be confused by now. So are people in the field.
Our own environmental unit of the Marquette County Health
Department, which is a very well run section, staffed by educated, experienced
sanitarians, is in internal disagreement on this issue. But the law
will require changes and those changes which are necessary will be enforced,
I bet.
I have treated this matter seemingly somewhat lightly, but
the contamination problem is a very serious one and grows worse with
the proliferation of food service operations and untrained and, most
importantly, unmanaged workers.
I think, however, that with some minor exceptions, the insistence
on gloves everywhere borders on ludicrous. In almost all areas of our
existence we live in a technology culture. If we find a problem, "technology":
will fix it. However, "clean hands" is not a technology matter.
And gloves will not fix the basic problem, but only cover it up.
Quite possibly the answer to all this was stated by Fred
Reimers (only half-jokingly) of the aforementioned Texas grocery chain:
maybe, he said, workers should put gloves on when they enter the bathroom
and throw them away when they come out.
And also, in the food safety area:
Come November the requirement for refrigerator temperature will drop
from the current 45 degrees to 41 degrees. Also, requirements for establishments
preparing food will be the same whether the business is under the inspection
of the Agriculture Department or the Health Department. This has been
a big area of non-compliance on the part of many if not most of those
businesses under Agriculture, primarily gasoline stations and quick-stop
places whose sales from food represent less than fifty percent of their
business. Ventilation and return air requirements need to be equalized.
Now the problem will be getting enough Agriculture inspectors to get
around to the gas stations, some of whom are very bad, indeed. I certainly
don't want to tar all of them, because several I know are clean and
properly run (except for ventilation). But most would not now pass the
inspection of the Marquette County Health Department inspectors I have
dealt with.
But it's progress, anyway.
