These instructions were issued after a meeting in Karachi on Saturday evening between the officials of Pakistan Agriculture Seed and Storage Corporation (Passco) and Australian Wheat Board (AWB), which was chaired by the minister.
He had dashed to Karachi on Saturday evening to resolve the deadlock between the Passco and AWB over the quality of wheat.
Accordingly, two teams comprising of Pakistani and Australian experts will proceed to vessels at 8:00am Sunday morning to take out samples which will be sent for testing in laboratories in Karachi and Islamabad.
Two ships carrying rejected stuff, and a third ship, are waiting at the outer anchorage at Port Qasim.
The third ship, m.v. Federal Hudson, carrying about 40,000 tonnes of wheat arrived at Port Qasim on Thursday evening, while the quality of wheat brought earlier by two vessels was found unfit for human consumption due to presence of "karnal bunt" disease. Samples have not yet been drawn from the third vessel.
Elaborating on the sampling and testing procedure, a spokesman of Pascco said that the samples from the earlier vessels were drawn in the presence of the International Testing Services, representing the sellers, and were sealed by them and dispatched to Islamabad for testing.
He said that out of a total of eight test results, six tests were positive, confirming the presence of "karnal bunt."
Senior testing experts later confirmed the results. The wheat was also found containing "wet gluten" at a ratio ranging from 20.4 to 22.6 percent against an international standard of 26 percent.
The spokesman said that the disease "karnal bunt" was commonly found in wheat produced in India, "therefore we did not buy the commodity from India, which was available at 185 dollar to 190 dollar per tonne against the Australian price of 224.75 dollar per tonne.
"We have an open offer to Tradesman International for a joint inspection and testing of wheat as was done earlier. This time we offer them to take the samples jointly to Islamabad and get it tested in their presence", he concluded.
