12/1/2023 Direct call from consumer. The following has been spontaneously reported by the caller. Caller was only able to verify product by name. Roundup Paraquat Classic. Caller is son reporting his father has been diagnosed with Pulmonary fibrosis and has been admitted to the hospital. Caller states x-ray, computed tomography, magnetic resonance imaging, ultrasound, and blood work have been done. Caller is not sure of the exact results but states his father has been diagnosed with Pulmonary fibrosis. Caller is inquiring if this product could have potentially lead to his fatheras diagnosis. Caller reports his father has been using this product on the family farm for 40 plus years. Caller states the product was diluted with water but he's not sure of the dilution rate. Caller reports the dilution amounts may have changed over the years. Caller was in the hospital and the reception was very poor. No additional details regarding symptoms and treatment was collected due to poor reception. Caller disconnected while on hold. Attempted callback one: Call rang a couple of times then went to dead air. Attempted callback two: Voicemail has not been set up. Unable to leave a voicemail message.

Company causality assessment: 1 (unlikely relationship). The product was reported as aRoundup Paraquat Classic,a and could not be identified by EPA number or otherwise, and no further information was able to be obtained. It is likely the caller is referring to three separate products, RoundUp (BayerCrop Science), Classic Herbicide (Corteva) and another unknown product with the active ingredient paraquat. Little information was provided regarding product(s) use, dilution, or exposure. It is unclear if and how the consumer would have been exposed. RoundUp branded products typically contain glyphosate as the active ingredient and small inadvertent exposures during directed use are unlikely to result pulmonary fibrosis. Classic Herbicide contains the active ingredient chlorimuron-ethyl and although small inadvertent exposures after dilution with water as directed on the label is unlikely to result in pulmonary fibrosis it is of note that the product contains quartz. Inhalation of quartz in repeated dose toxicity studies in rats have reported chronic lung conditions and fibrosis. It is well documented that paraquat can cause pulmonary fibrosis and lung injury. Type I and types II pneumocytes selectively accumulate paraquat and causes redox cycling and production of toxic reactive oxygen species. This leads to cellular damage and pulmonary fibrosis. Most of the cases resulting in severe toxicity occur after ingestion. Paraquat is not well absorbed through intact skin and is typically only life threatening after exposure to non-intact skin or in prolonged exposures. Inhalational of sprayed paraquat can cause lung irritation but rarely results in systemic absorption. Given the lack of a known reported exposure and limited information all other differential diagnosis need to be considered and further information would be necessary to complete a full analysis.As the reporter did not identify a specific product alleged to have caused the exposure, Bayer has chosen to report this exposure using the product in this report using the information it had available, including reported use and market share. This selection may not be accurate due to the lack of information provided by the reporter.Sukumar CA, Shanbhag V, Shastry AB. Paraquat: The Poison Potion.
