All samples taken from Ghazipur chicken market test negative for bird flu: Official NEW DELHI : All 100 samples taken from the Ghazipur poultry mandi, Asia’s largest chicken market, have tested negative for bird flu, officials said on Thursday. The results come three days after samples taken from crows and ducks in the national capital tested positive for avian influenza. This had led to the Delhi government on Monday banning the sale of processed and packaged chicken brought from outside the city. The government had also shut down the poultry market for 10 days as a precautionary measure. “Test results of 104 samples arrived on Wednesday evening. Of these, 100 samples were collected from 35 poultry birds in the Ghazipur market. All samples have tested negative for bird flu,” senior Animal Husbandry Unit officer Rakesh Singh said.
