[Survey of Arsenic/Heavy Metals and Pesticide Residues in Edible Insects for Human Consumption or Supplied in Japan].

ABSTRACT

Arsenic (As) and heavy metals (Cd, Hg, Pb, and Cu) and pesticide residues in 14 edible insects were investigated. The maximum levels of elements were 6.15 for As, 0.82 for Cd, 0.50 for Hg, 0.67 for Pb, and 297.7 ppm for Cu. Fenobucarb (or BPMC) has been quantified through GC- and LC-MS/MS analysis at a concentration of approximately 3 ppm. Further studies of the contaminants may help ensure the safety of edible insect consumption.
