The diagnose of paraquat intoxication was based on the information provided by the care taker and the symptomes as described above.
Paraquat intoxication in humans (CDC | Facts about Paraquat):
Paraquat is a toxic chemical that is widely used as an herbicide (plant killer), primarily for weed and grass control. Paraquat causes direct damage when it comes into contact with the lining of the mouth, stomach, or intestines. After paraquat enters the body, it is distributed to all areas of the body. Paraquat causes toxic chemical reactions to occur throughout many parts of the body, primarily the lungs, liver, and kidneys.
Cells in the lung selectively accumulate paraquat likely by active transport.
Immediately after ingestion: pain and swelling of the mouth and throat.
Severe gastrointestinal symptoms, followed by dehydration, low blodd pressure.
Ingestion of small amounts may result in:

Foraging elephants poisoned by paraquat

CHIANG MAI: Seven elephants suffered serious burns to their mouths and tongues from eating grass contaminated with the herbicide paraquat at a border village in Omkoi district.
Five of them were reported to be in critical condition.
The paraquat poisoning occured at Khorphator village late on Thursday night. The domesticated elephants had been set free to forage for food, and ate the grass at nearby farms which had been sprayed with the banned chemical.
Veterinarians and rescue workers were rushed to help after the elephants' distress was reported to Chiang Mai University’s Centre for Elephant and Wildlife Research and to the Kusol Songkhor rescue foundation.
It took several hours for the team to reach the remote village, which is near the border.
The vets examined the animals and diagnosed paraquat poisoning. The chemical had caused severe burning around their mouths and to the animals' tongues.
They cleaned the injuries and gave the elephants anti-inflammatories.
Five of them were diagnosed in critical condition. They were being trucked to the Elephant Hospital in Lampang for further treatment, the Thai Elephant Alliance announced on its Facebook page.
The Centre for Elephant and Wildlife Research said the first three had already arrived at the hospital. The others were expected to arrive on Friday evening.
The use of paraquat is illegal in Thailand. The NHSC issued a resolution banning the use of paraquat and chlorpyrifos in agriculture, effective from June 1 last year. Farmers' groups have lobbied strongly against the ban, arguing they have no alternative chemicals for insect and weed control. Many continue to use them.
