*

Indicates that the MRL is proposed at the limit of quantification.

n.a.: not applicable; n.r. : not reported.

a

Median residues expressed according to the residue definition for monitoring, recalculated at the 1N rate for the median dietary burden.

b

Highest residues expressed according to the residue definition for monitoring, recalculated at the 1N rate for the maximum dietary burden.

c

Closest feeding level and N dose rate related to the maximum dietary burden.

d

Considering that tentative processing factors for potatoes process waste and dried pulp were used to calculate the dietary burdens and potatoes were the main contributor of the livestock exposure, the derived MRLs for livestock should be considered tentative only.

e

Since extrapolation from cattle to other ruminants and swine is acceptable, results of the livestock feeding study on ruminants were relied upon to derive the MRL and risk assessment values in sheep and swine.
