| Conclusions
There is bound to be a suspicion that because the United
States Government had advocated the use of (mainly) latex
barriers to avert a health risk which it perceived to be
of catastrophic dimensions (the AIDS epidemic) that the
same governmental forces would be thrown at any perceived
consequence of this action (the latex protein allergy problem).
Thus the various political measures which are being employed
to restrict the use of latex gloves, many of which are manifestly
unfair, especially those relating to the non-medical use
of latex gloves, have to be balanced against the increase
in market for latex barriers which was created by the FDA's
reaction to the AIDS epidemic.
Many of the alternative materials being proposed are questionable
either because they fail to act as an effective barrier,
or because they are potentially dangerous, or are perceived
to be potentially dangerous in Europe. Vinyl gloves are
potentially dangerous both through being based on a chlorinated
polymer and for containing plasticisers: as noted earlier
they are also ineffectual barriers against pathogens. The
disposal of chlorinated polymers is an increasing cause
for concern (although this may also affect chlorinated natural
rubber latex gloves).
American farmers are probably the most powerful political
lobby on this planet as is evidenced by the current battle
at the World Trade Organization between the Americans who
wish to export beef from hormone-treated cattle, and the
Europeans who have decided that such hormone treatment is
potentially dangerous. Similar battles may be expected over
genetically modified crops. Such a body would not be willing
to hear any "derogatory comments" concerning corn
or starch from a US governmental agency, even though this
is a prime suspect in the latex protein saga. Moreover,
although far more Americans, many of whom are infants, routinely
die through eating peanuts than will ever die from an allergic
reaction to latex. Peanuts are grown on a vast scale in
the USA, whereas latex comes from some "obscure"
tropical countries. Furthermore, it should be noted that
both of the protagonists in such battles (a further one
is the export of British beef, which may be affected by
BSE, to France) tend to quote scientific evidence.
At a recent rubber conference in Manchester Haydn Williams4
closed his contribution by noting that :"The casual
reader or web surfer on the subject of latex allergy could
easily form the impression that there is a crisis of epidemic
proportions. This is not so. While in no way denying the
very real suffering of some individuals due to allergy,
it must be remembered that such individuals are in a small
minority. Billions of gloves are used annually in protecting
healthcare workers from the very real threat of infection
by deadly viruses and antimicrobial resistant micro-organisms.
Natural rubber latex, furthermore, is universally agreed
to be the best barrier to such organisms. These are essential
uses that have very real positive consequences for those
at risk of infection. The enormous amount of independent
research and international collaboration on understanding
the issues involved in latex allergy is bearing fruit. Standards
to control allergen levels are and will be developed, and
processes are in place to bring about product improvements.
Continued efforts in this direction coupled with education
of end users will lead to a continued reduction in risk
of sensitisation and result in a situation where the vast
majority of NR glove users can continue to do so with confidence
that they have the best and safest barrier to infection
on their hands".
Environment friendly latex gloves
Environment-friendly natural rubber gloves by A. Ikram
(Malaysian Rubber Board Monograph No. 2) compares the natural
biodegradation of glove pieces made from natural rubber,
polychloroprene, nitrile and vinyl after burial in two types
of soil. After one year the bulk of the natural rubber films
had biodegraded, but this was not the case for any of the
synthetics, although the thin vinyl films did start to degrade
presumably due to the presence of plasticizer and the inherent
weakness of the films.
