Researchers with the Vaccine and Infectious Disease Organization expect to be ready to begin field trials of new bovine tuberculosis vaccines within the next couple of years. Bovine tuberculosis is a contagious bacterial infection, primarily of livestock but it also affects other mammals like wildlife species, and it can spread from mammals to humans.

Dr. Jeffrey Chen, a Research Scientist with VIDO at the University of Saskatchewan says because TB is highly transmissible and poses a serious risk to the public, Bovine TB is reportable and if Canada was to be affected it would shut down the cattle industry resulting in disastrous economic consequences.

It's going to take weeks to clear the backlog of traffic as a result of the B.C. port strike. A lot of cargo is sitting waiting to be loaded onto vessels and moved out of the port.

CN's assistant vice president of grain, David Przednowek says the strike caused a number of delays for traffic flow but the focus now is on implementing an orderly plan to resume carloads and intermodal movements. He says there's all kinds of traffic that was stalled in the port that's got to move inland east, and traffic that's loaded that wants to move west.

He says for every day that the supply chain was shut down it will take many days to get back to normal.
