Under the new program, farms with herds that test negative for three consecutive weeks using bulk tank milk samples will be able to move cattle without additional pre-movement testing, USDA said.
Construction of the interceptor system required 318 million bricks, 2.7 million cubic metres of excavated earth and 670,000 cubic metres of concrete. [88] Gravity allowed the sewage to flow eastwards, but in places such as Chelsea, Deptford and Abbey Mills, pumping stations were
