Fumigation of cargo becomes very essential because there are possibilities of hidden infestation in the cargo, which is being exported. It can happen due to following factors.
(a) The infestation develops due to high moisture level in the cargoM
(b) It depends on the place of storage prior to shipment
(c) It happens during the time of transit due to previous cargo residues, which might exist in the container/ Ship holds
The infestation rapidly develops during the voyage period and when the cargo reaches port of discharge it is re-fumigated again at the cost of exporter/ buyer. It is always good to carry out fumigation prior to export to avoid huge fumigation and handling cost at the port of discharge
Un-treated packing materials are prone to infestation and they become carriers for introducing new pests to another Country.
