(June 3, 4:57 p.m.) The New Mexico Department of Health is looking closely at Mexico as the source of tainted tomatoes in an investigation of an outbreak of Salmonella Saintpaul that has sickened at least 40 people in New Mexico and Texas.

“It’s really preliminary at this point, but New Mexico gets most of its tomatoes from Mexico at this time of year,” said Deborah Busemeyer, the state agency’s communication’s director. “Preliminary indications are that the tomatoes are from Mexico.”

Busemeyer said that 19 people in that state have suffered Salmonella Saintpaul infections with the same genetic fingerprint as 21 victims in Texas. She said New Mexico is investigating 17 other cases that could be related.

Food and Drug Administration spokesman Sebastian Cianci said there have been a total of 17 hospitalizations in Texas and New Mexico. Federal and state agencies also are investigating whether 30 cases in Arizona, Colorado, Idaho, Illinois, Indiana, Kansas and Utah are associated with tomatoes.

No deaths have been reported in any of the states, Cianci said.
