(from the CDPH) Monocrotophos, a dangerous pesticide banned from the U.S. has been discovered on recently imported cactus samples at amounts as large as 5.8 parts-per million.
The CDPH states that customers must either send these back to the vendor they purchased them from, or dispose of these rather than attempting to clean off the pesticide.
No health issues have been reported as of yet, but signs of acute poisoning can contain perspiration, headache, weakness, nausea, emesis, hypersalivation, stomach cramps, and diarrhea. Ingestion of monocrotophos (the above pesticide) can result in neurotoxicity and irreversible nerve injury.
The CDPH says they are operating together with the US Food and Drug Administration to recognize responsible parties in order that future goods might be more carefully analyzed.
The CDPH urges consumers experiencing any bad effects after consuming cactus merchandises to consult their physician.
