Bernie Sanders concedes the Missouri primary to Hillary Clinton, who led by 1,531 votes, 0.2 percent of those counted. Sanders says he will not ask for a recount, an option he had because the result is under the state's requirement, 0.5 percent — one-half of one percent. The Republican contest is too close to call as Donald Trump leads Ted Cruz by a similar 0.2 percent.

U.S. federal health officials are investigating an outbreak of deadly E. coli bacteria that has sickened 19 people in California, Colorado, Missouri, Montana, Utah, Virginia, and Washington. Preliminary evidence suggests that rotisserie chicken salad made and sold in Costco Wholesale stores is the likely source. This follows a totally unrelated outbreak earlier this month connected to Chipotle Mexican Grill restaurants. Those restaurants have been cleaned, new ingredients ordered, and have been reopened. The Costco E. coli 157 strain, which has caused five people to be hospitalized- two of which developed hemolytic uremic syndrome (HUS; which can readily lead to acute renal failure and sepsis), is more dangerous than the Chipotle E. coli 026 strain, though there have been no deaths yet.
