MARSHALLTOWN, Iowa (AP) — Iowa authorities say 15 agricultural workers were exposed to a herbicide while working north of Conrad in Grundy County. The workers were in a field when herbicide from a ground sprayer blew onto them Thursday afternoon. They were taken to Central Iowa Healthcare in Marshalltown, where a decontamination area was set up in the hospital parking lot. Many of the workers complained of sore throats and itchy eyes. They were then taken inside for emergency treatment after they removed their clothes and washed off.
All the workers were expected to leave the hospital by Friday afternoon. It's unclear what herbicide was involved.
