Most ill in – Arizona 42, California 66, Colorado 50, Texas 13 and Utah 9.

According to the CDC, as of November 15, 2018, 246 people infected with the outbreak strain of Salmonella Newport have been reported from 25 states. Arizona 42, California 66, Colorado 50, Connecticut 1, Hawaii 4, Idaho 3, Iowa 1, Illinois 1, Indiana 1, Kansas 1, Kentucky 1, Massachusetts 1, Minnesota 2, Missouri 3, Montana 8, New, Mexico 9, Nevada 3, Ohio 9, Oklahoma 4, Oregon 1, South Dakota 6, Texas 13, Utah 9, Washington 3 and Wyoming 4.

Illnesses started on dates ranging from August 5, 2018 to October 16, 2018. Ill people range in age from less than one year to 88, with a median age of 38. Fifty-six percent are male. Of 168 people with information available, 59 (35%) have been hospitalized. No deaths have been reported.

Illnesses might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 2 to 4 weeks.

Whole genome sequencing analysis did not identify predicted antibiotic resistance in 180 Salmonella bacteria isolates from 176 ill people and four food samples.

State and local health departments continue to ask ill people questions about the foods they ate and other exposures in the week before they became ill. Of 137 people interviewed, 123 (90%) reported eating ground beef at home. This percentage is significantly higher than results from a survey of healthy people in which 40% of respondents reported eating any ground beef at home in the week before they were interviewed.

Epidemiologic, laboratory, and traceback evidence indicates that ground beef produced by JBS Tolleson, Inc. is a likely source of this outbreak.

On October 4, 2018, JBS Tolleson, Inc. recalled approximately 6.9 million pounds of beef products that may be contaminated with Salmonella Newport.

Officials in Arizona collected an unopened package of ground beef from an ill person’s home. The outbreak strain of Salmonella Newport was identified in the ground beef. Whole genome sequencing showed that the Salmonella identified in the ground beef was closely related genetically to the Salmonella in samples from ill people. The ground beef was one of the products recalled on October 4, 2018.
