USDA’s Animal and Plant Health Inspection Service (APHIS) approved the importation of commercial shipments of fresh mangoes from Pakistan in August 2010.To ensure that plant pests of quarantine significance do not enter the United States, the mangoes must be treated with specified doses of irradiation at an APHIS-certified facility.Irradiation treatment may be applied prior to or upon arrival into the United States. In addition, each shipment must be accompanied by a certificate issued by the national plant protection organization of Pakistan with additional declarations certifying that the consignment was inspected and found free of the causal agent of mango bacterial black spot, Xanthomonas campestris pv.mangiferaeindicae. The fruit will also be subject to inspection at the port of first arrival into the United States.
The proposed source of irradiation is Cobalt-60. The minimum dose for this treatment is 0.15 kGy and the maximum dose is 0.30 to 0.45 kGy, depending upon the type of irradiator employed (pallet or carrier, respectively).2Another purpose of the irradiation is to control the mango seed weevil, in which case the minimum dose is 0.30 kGy and the maximum doses 0.60 and 0.90,For commercial disinfestation, therefore, the range proposed by the petitioner is 0.15 kGy to 1.0 kGy.
