In December 2017 Washington State Department of Health announced an outbreak of Salmonella infections linked to consumption of pre-cut watermelon, cantaloupe, or fruit mixes containing watermelon or cantaloupe. Twenty four cases from Washington (21) and Oregon (3) were identified. Known onset dates ranged from October 28, 2017 to December 6, 2017. There were 6 reported hospitalizations and one death, but it was not attributable to their salmonellosis.

Most cases reported purchasing cut melons from Fred Meyer and OFC grocery stores. Product traceback identified Mary's Harvest Fresh Foods as the supplier of the cut fruit. An environmental sample taken at Mary's Harvest by FDA inspectors yielded the outbreak strain which was highly related by whole genome sequencing to clinical isolates.
