DIOXIN FORUM HELD BY MINNESOTA FOOD ASSOCIATION

On August 8, 1995 the Minnesota Food Association held a Member Forum on "Dioxin
in the Food Supply". In attendance were Minnesota Food Association members,
representatives of other organizations in the area working on dioxin-related
issues, and concerned citizens.

Two panelists were invited to address the forum. Toxicologist Dave Belluck from
the Mn Pollution Control Agency explained that dioxin is the name for a large
group of chemical compounds which are the by-products of many chemical,
manufacturing and combustion processes (most notably waste incineration). These
compounds are of concern for their effects on human health because 1) they are
long-lived; that is, they do not break down quickly; 2) they accumulate in the
fatty tissues of animals and humans; and 3) they are distributed all over the
earth.

Discussion confirmed that indeed all humans carry some level of dioxin in their
bodies. Since there is no dose at which no effects occur, Belluck explained,
there is no "safe dose "of dioxin. Over time, continual low level exposures
"build up" until adverse health effects begin.

Belluck pointed out that in its recent reassessment of dioxin, the Environmental
Protection Agency identified both cancer and non-cancer effects for dioxin. The
EPA estimates that the lifetime risk of getting cancer from dioxin exposure is
between one in 1,000 and one in 10,000. Dioxin is also linked to severe
reproductive and developmental effects and damage to the immune system.
Infertility, birth defects, impaired child development, diabetes, endometriosis
and thyroid changes are linked to dioxin exposure. Belluck noted that because
the EPA has decided not to issue a "non-cancer toxicity factor", no risk
assessments will be made for the non-cancer effects of dioxin.

It is chiefly through our food supply that humans are exposed to dioxin, Belluck
explained. Dioxin gets into the food supply as follows: it is released into
the air from waste incineration, pulp and paper processing, and the manufacture
of plastics. Then it settles onto the soil, water and plants and is eaten by
animals. Dioxin accumulates in their fatty tissues and is consumed as part of
our diet. The EPA says that 90% of human exposure occurs through diet, with
foods from animals being the chief source.

Panelist Jackie Hunt Christensen from the Institute for Agriculture and Trade
Policy added crucial information as to the non-cancer effects of dioxin in her
remarks . She also pointed out that in the laboratory, chemicals are tested one
at a time for their toxic effects, but that in actuality, we are exposed to a
mixture of chemicals. Both the accumulation and the combination of these
compounds is cause for concern, she said.

Reminding the audience that any use of chlorine in industrial processes,
including incineration, results in dioxin formation, Hunt Christensen discussed
ways of removing chlorine from use. She said that Europeans are leading the way
in producing paper without using chlorine and that she is aware of one mill in
the US which makes chlorine-free paper. She also mentioned the use of ozone or
ionization for purifying water systems and new water-based "wet" dry-cleaning
processes.

Hunt Christensen encouraged those attending not to be intimidated by the
complexity of the issues around dioxin. You don't have to be a scientist to
question the effects of dioxin on human health, she explained. "I eat, so I am
concerned." Our legislators are determining regulatory policies and enacting
laws for environmental and health agencies, she pointed out, and they are not
scientists. She urged citizens to become informed and then educate their
legislators.

Discussion and questions from the audience revealed much potential for
coalition-building among those attending this Forum. Several people voiced
awareness that concern for safe food cannot be separated from issues concerning
deteriorating human, animal and planetary health. MFA provided those attending
a list of organizations, both national and local, which are currently working on
dioxin-related issues and from whom further information is available. The list
is included in this posting.

MFA will also take the lead here in the Upper Midwest, along with the Institute
for Agriculture and Trade Policy, in convening follow-up meetings with
interested groups and individuals to explore the creation of coalitions around
the control of dioxin. We welcome expressions of interest in this
coalition-building effort as well as any further information you feel would be
of help to us.
