Tests at a cantaloupe-processing plant in Mexico came back negative for salmonella, as health officials ordered the temporary closure of the plant and took samples in response to a deadly outbreak in the US and Canada. A new analysis of water, product, and surface samples will be conducted in February, while at least 11 deaths have been linked to the outbreak, with recalls of the Malichita- and Rudy-branded cantaloupes issued. The US Centers for Disease Control and Prevention reported 4 deaths, while Canada's public health agency reported 7.
