World
Health Organization [WHO] (1992) reports that roughly three million pesticides
poisonings occur annually and results in 220,000 deaths worldwide. Both
economically and in terms of human life these poisonings represent an enormous
cost for society.

Pesticides
as the world implies can be defined as chemical substances used to destroy or
control invasion of pests in agriculture. According to Akpoguma (2003),
pesticides are Agro-chemical biologically active used in control of pest,
through their destructive consequences.

(2005) defined pesticides as non-degradable organochlorides and organophoshates
chemicals which when used against pest in the environment harm indiscriminately
with their persistence consequences.

From
the above definition of pesticides, it became obvious that in order to kill
unwanted insects, weed or rodent, pesticides have to be poisonous but the
poison cannot be limited to the unwanted weed or insect pest only.

Studies
from all over the world show that pesticides harm indiscriminately at all
stages namely, during manufacturing, application and consumption of pesticides
treated product (Voluntary Health Association of India, 2000). However the
three main types of pesticides on focus in this study are insecticides,
herbicides and fungicides.

Over
the years, the use of pesticides has a major contribution to the welfare of
man, in that they have been responsible for tremendous increase agricultural
output and for the control of previously widespread and crippling disease among
animal and crops. But recent research has shown that the benefit derived from
the use of pesticides used to he balanced against the actual and potential cost
of their use.

The
use of chemical to control pest will also lead to the eradication of other
vital organisms in the environment, which may be of agricultural importance.
This may result in rendering pollinating insect few and chemical enter the
soil, they may destroy earthworms and other soil organisms responsible for the
breakdown of organic matter.

Poisoning
result from the use insecticide (pesticides) and poison baits to kill rat
pests; such chemical may be taken in by the animals or man himself either
directly or indirectly. Animals and man feeding on the crops on which these
chemicals have been sprayed may be poisoned. Also, man feeding on the animals
like cattle, birds or wild animal killed by the poison can be poisonous and
often fatal.

More
than 600kg of pesticides chemicals are applied annually in Obiaruku in Ukwani
Local Government Area. It is therefore important to carry out this study in
order to determine the public health implication of pesticides on farm products
in Obiaruku Local Government Area of Delta State.
