ABSTRACT:
Disclosed is a method for killing animal pests infesting a water-bearing product and including placing the product in a chamber having at least some oxygen therewithin and reducing the pressure in the chamber below atmospheric pressure. The improvement comprises the steps of reducing the pressure in the chamber at least to the boiling point of the water in the product so that oxygen in the chamber is displaced by water vapor until the chamber is substantially oxygen depleted. The oxygen depleted condition is maintained for the "time of lethality," i.e. for a time at least equal to the time required for a pest to be killed in an oxygen-depleted environment. Specific aspects of the new method also involve using inert gas and a poison gas fumigant.
