MRL: maximum residue level; CF: conversion factor for enforcement residue definition to risk assessment residue definition; STMR: supervised trials median residue; HR: highest residue; bw: body weight.

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

n.a.: not applicable.

n.r.: not reported.

a

The mean residue level for milk and the median residue levels for eggs and tissues were recalculated at the 1N rate for the median dietary burden.

b

The mean residue level in milk and the highest residue levels in eggs and tissues were recalculated at the 1N rate for the maximum dietary burden.

c

As reported residue levels were analysed according to the residue definition for risk assessment, a CF of 1 is proposed from enforcement to risk assessment.

d

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

e

Highest residue level from day 1 to day 28 (daily mean of 3 cows).

f

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.
