Agricultural commissioners in two Central Valley counties have launched investigations into two apparent chemical releases that sickened dozens of fieldworkers over the last nine days.
The latest incident took place in Fresno County on Thursday morning when a group of farmworkers picking nectarines began feeling sick after several pesticides had been sprayed on a nearby field. That came nine days after several other farmworkers in Tulare County reported feeling ill at the end of their shift, possibly because of a chemical drift.
At least 32 workers complained of symptoms in the two cases, although scores of others working alongside them may have been exposed to chemicals as well.
Investigators are specifically trying to determine if a pesticide sprayed on a nearby field drifted to the field where the workers got sick.
The incident on Thursday took place in the town of Kerman, west of the city of Fresno. Some 29 workers complained of symptoms that included vomiting, headaches and itchy eyes and throats, according to Stace Leoni, the county's deputy agricultural commissioner. Three of the employees were hospitalized, she added.
Leoni said the chemicals that were sprayed in the vicinity of the workers included Nealta miticide, Zylo insecticide and summer oil, a substance that helps the chemicals stick to the leaves of crops.
None of the chemicals are considered "California restricted materials," so the company that applied them was not required to provide county officials with advance notice they would be used, according to both Leoni and Charlotte Fadipe, a spokeswoman for the California Department of Pesticide Regulation.
Leoni declined to release the name of the agricultural company that applied the chemicals.
The farmworkers in the latest incident are employed by Gerawan Farming, one of the nation's largest growers of peaches, plums and nectarines. The Fresno-based company said it responded quickly once it got word that some of its employees were not feeling well and that its crews were not given a heads-up about pesticides being applied in the area.
