Since April, 613 persons infected with Salmonella Saintpaul with the same genetic fingerprint have been identified in 33 states and the District of Columbia. These were identified because clinical laboratories in all states send Salmonella strains from ill persons to their State public health laboratory for characterization.

The marked increase in reported ill persons since the last update is not thought to be due to a large number of new infections. The number of reported ill persons increased mainly because some states improved surveillance for Salmonella in response to this outbreak and because laboratory identification of many previously submitted strains was completed. In particular, one new state, Massachusetts reported ill persons.

The number of ill persons identified in each state is as follows: Arkansas (3 persons), Arizona (34), California (8), Colorado (4), Connecticut (4), Florida (1), Georgia (14), Idaho (3), Illinois (45), Indiana (9), Kansas (9), Kentucky (1), Maryland (18), Massachusetts (12), Michigan (4), Missouri (12), New Hampshire (1), New Jersey (1), New Mexico (79), New York (18), North Carolina (1), Ohio (3), Oklahoma (17), Oregon (5), Pennsylvania (5), Rhode Island (2), Tennessee (4), Texas (265), Utah (2), Virginia (21), Vermont (1), Washington (1), Wisconsin (5), and the District of Columbia (1).

Among the 316 persons with information available, illnesses began between April 10 and June 13, 2008. Patients range in age from <1 to 99 years; 50percent are female. At least 69 persons were hospitalized. No deaths have been officially attributed to this outbreak. However, a man in his sixties who died in Texas from cancer had an infection with the outbreak strain of Salmonella Saintpaul at the time of his death. The infection may have contributed to his death.
