Investigators from the federal Centers for Disease Control and Prevention along with Texas health officials are still seeking the source of a severe stomach illness that has sickened 283 people in the state.
Texas Department of State Health Services spokeswoman Christine Mann says new cases of cyclospora infection are being confirmed daily, but none have onset dates after July. Reports began coming in mid-July from the Dallas-Fort Worth area.
Mann says Texas would typically see 10 to 12 cases annually. The parasite has historically been found on imported produce.
Officials have not determined whether the Texas cases are connected to a multi-state outbreak that sickened more than 600.
The federal Food and Drug Administration said Tuesday a farm in Mexico linked to the outbreak in two states could resume operations.
