Crops grown with the use of methamidophos include potatoes[1] and some Latin American rice.

It is rapidly absorbed through the stomach, lungs, and skin in humans, and eliminated primarily through urine.

[5] Rice–fish culture is common in the southern parts of China as well as in many other rice-producing countries (e.g., Thailand, Malaysia, and the Philippines).

Both plants and animals did not degrade the pesticide well, and fish for human consumption in these cases contains methamidophos in concentrations roughly similar to brown rice.

[5] Methamidophos was found in dumplings (gyoza) manufactured in China for the Japanese market after a number of consumers became sick.
