There was a strong odor, and liquid could be seen on the grass and furniture. After playing outdoors that afternoon, her child developed nausea and vomiting, with some sweating but no fever. She also had mild tremors. Her pediatrician diagnosed her child with “flu” (GI virus). However, she is asking you if you think the pesticides may have had something to do with her child’s illness.
