14. Severity classification.


15. Provide supplemental information here.

The estimated amount of product, reported to have been intentionally ingested, was approximately 4-7 fl. oz. (120-210mL). The product contains 18% ispropylamine salt of glyphosate, 0.73% diquat and a surfactant resulting in a potential ingestion of 37.8 grams and 1.53 grams respectively. The reported signs and symptoms are in line with reports of intentional ingestions of glyphosate containing products and diquat. After ingestions of less than 1 gram of diquat, oral and pharyngeal irritation, nausea and repeated vomiting have been reported. Severe toxicity may develop with ingestions of more than 1 gram resulting in renal impairment, toxicity to all organ systems and death within 24-48 hours. Ingestions of glyphosate/surfactant containing products can cause irritation to the gastric mucosa, nausea, vomiting, and abdominal pain. More serious toxicity can occur in large or deliberate ingestions, most often 200mL, including, pulmonary edema, respiratory failure, ventricular dysrhythmias, and coma. Severe toxicity resulting in death has been related to hypovolemic shock followed by respiratory failure. Additionally, a temporal relationship exists between the time of the reported ingestion and onset of symptoms. It was reported that no other substances were have known to be ingested and while not confirmed with the treating healthcare team all other obvious causes appear to have been ruled out.
