Safety
Organic farmers are not
allowed to use synthetic pesticides,
herbicides, fertilizers, genetically
modified organisms or fertilizer derived
from
sewage sludge on
their crops, nor are they allowed to
irradiate their seeds or the foods
they produce. These guidelines are
strictly monitored and enforced,
meaning that organic vegetables are
free of chemical residues and
questionable practices that have been
linked to all kinds of human health
problems.
In addition to the toxic nature of many
inputs used in conventional agriculture,
there is a major, and disgusting practice
that many people might not know about.
Conventional farmers are allowed to
fertilize their fields with sewage sludge
from waste treatment plants, even though
this material has been proven to contain
traces of heavy metals and other
pollutants. There is no clear consensus on
the impact of this practice over time; how
high will the levels of heavy metals in the
soil go, will they be washed down into the
subsoil, taken up by the growing plants and
eaten, or a little of both?
Combined with the sewage sludge issue is
the uncomposted manure problem. Organic
farms are follow
strict guidelines
concerning the use of manure: it must
be composted pre-use, or applied 90
days before harvest if an edible
portion of the crop is in contact with
the manure. These regulations make
sense, because they eliminate the
spread of pathogenic bacteria such as
e. coli from the manure, to
the vegetable, to the consumer. Too
bad conventional farmers don’t have to
follow the same rules! We are seeing
increasing numbers of news reports
concerning illnesses and deaths caused
by
e. coli from vegetable
sources. This can be caused by
contaminated water or by improper use
of manure, either way, eating organic
vegetables will save a lot of
heartache, and stomachache too!
