US public health officials have confirmed that dozens more people have parasitic infections linked to trays of fresh, pre-cut vegetables that Del Monte Fresh Produce recalled in mid-June. The case count stands at 185, having increased by more than 100 since the outbreak was announced by the Centers for Disease Control and Prevention on June 15. Seven people have been so sick that they had to be admitted to a hospital.

Additional people are likely to be added to the CDC’s case count. It usually takes 2 to 14 days after a person ingests the Cyclospora parasite for symptoms to develop. Specialized lab tests are required to confirm cyclosporiasis. Lab results must be confirmed and then reported to state officials who send reports to the CDC.

Del Monte has recalled 6-ounce, 12-ounce, and 28-ounce vegetable trays containing pre-cut fresh broccoli, cauliflower, celery sticks, carrots and dill dip. Recalled products were sold in clear, plastic clamshell containers. All of the recalled products had best-by dates of June 17 or before.

According to foodsafetynews.com, state and federal officials continue to investigate the outbreak, but they have not yet determined the source of the parasites.
