1.1 These Recommendations have been compiled by
the Sub-Committee on Dangerous Goods, Solid Cargoes and Containers
under the direction of the Maritime Safety Committee of the International
Maritime Organization (IMO).
1.2 Insects and rodents on ships are objectionable
for various reasons. In addition to aesthetic and nuisance aspects,
pests may damage equipment and spread disease and infection, contaminate
food in galleys and food stores and cause damage to cargoes that will
result in commercial or other losses. Very few pesticides are suitable
for use against all kinds of pests that may occur aboard or in different
parts of ships. It is therefore necessary to consider the main categories
of pesticides individually.
1.2.1 Insects in cargo spaces and cargoes
1.2.1.1 Insect and mite pests of plant and animal
products may be carried into the cargo spaces with goods (introduced
infestation): they may move from one kind of product to another (cross
infestation) and may remain to attack subsequent cargoes (residual
infestation). Their control may be required to comply with phytosanitary
requirements to prevent spread of pests and for commercial reasons
to prevent infestation and contamination of, or damage to cargoes
of human and animal food.footnote In
severe cases of infestation of bulk cargoes such as cereals, excessive
heating may occur.
1.2.2.1 Rodents should be controlled not only
because of the damage they may do to cargo or the ship's equipment,
but also, as required by the international health regulations, to
prevent the spread of disease.
1.3 The following sections provide guidance to
shipmasters in the use of pesticidesfootnote with a view to safety of personnel and to
avoidance of excessive residues of toxic agents in human and animal
food. They cover pesticides used for control of insectfootnote and rodent pests in empty and loaded cargo
spaces, in crew and passenger accommodation and in food stores. Account
has been taken of existing recommendations of the World Health Organization
(WHO), the International Labour Organization (ILO), and the Food and
Agriculture Organization (FAO) of the United Nations, in regard to
pesticide residues and occupational safety.
