How bio detectives track a salmonella outbreak

When there's a salmonella outbreak, scientists do genetic sequencing on bacteria samples from infected patients and bacteria of the contaminated food product.

Centre for Disease Control lab discovered the salmonella outbreak linked to cantaloupe. In fact, the BCCDC was part of a number of labs to track the outbreak.
