Animal Residue Data Sheet - Cyfluthrin



Cyfluthrin, which includes beta-cyfluthrin is registered in Australia for use on Brassica vegetables, avocado, cereals, rape seed (canola), cotton, legume vegetables, pastures, pulses (chickpea, field peas, lupins, faba beans, navy beans-dried), alfalfa (lucerne), macadamia nuts, sorghum and tomatoes. Details of the registered use patterns can be found on the approved labels of registered products containing cyfluthrin and beta-cyfluthrin as the active constituent. This Animal Residue Data Sheet provides information on the possible residues in feed commodities obtained from crops treated with cyfluthrin, to provide assistance in the formulation of animal diets that should not result in the violation of animal commodity MRLs.

Current MRLs

The Australian MRLs for cyfluthrin in food and animal feed commodities listed in Table 1 and Table 4 of the MRL Standard [10 October 2002] are shown below. The residue definition of cyfluthrin and beta-cyfluthrin is cyfluthrin, sum of isomers.

Detailed information

All feed commodities

Feed commodities that may contain residues of cyfluthrin are listed in the table below. The theoretical maximum proportion of the diet that the commodity can comprise, when residues are present at the MRL, without the significant risk of animal commodity MRLs being violated is also given. For instance, if wheat bran, unprocessed were fed to cattle at 80 % of the diet, the diet would need to be free of residues of cyfluthrin to minimise the risk of cattle commodity MRLs being violated. It should be noted that the feeding levels assumed by the APVMA when setting animal commodity MRLs are theoretical values, and they should not be taken as recommendations of appropriate rations for livestock.

a The feed commodities that may contain residues of cyfluthrin, and may form more than 20% of an animals diet.
b The maximum % of the diet that the commodity is assumed to comprise for the purposes of setting MRLs, based on Stockfeed Information Document 1
c The equivalent amount of feed for an animal of designated weight and feed intake that is assumed for the purposes of setting MRLs
d The MRL for each feed commodity (correction for dry weight basis where required)
e The maximum intake of cyfluthrin when the commodity is fed at the maximum assumed level (Column 1) in the absence of other sources of cyfluthrin.
f The maximum % of the diet at which the commodity could theoretically be fed without significant risk of exceeding animal commodity MRLs. It is assumed that the residue in the feed commodity is present at the MRL (or dry weight equivalent) and other dietary sources of cyfluthrin are absent.

† Due to a lack of residue data for all pulse forages, the highest level found (1.4 mg/kg) was rounded up to 2 mg/kg and included in the calculation.

Abbreviations and definitions

DM: Dry matter. The feed consumption for livestock and the residue levels in feed commodities are expressed on a dry matter basis.

DDIL: Daily Dietary Intake for Livestock. The level of dietary exposure for a specified chemical in a specified species that should not result in exceedance of the relevant animal commodity MRLs. Expressed in mg chemical/kg bodyweight.

MFL: Maximum Feeding Level. The level of dietary exposure for a specified chemical in a specified species that should not result in exceedance of the relevant animal commodity MRLs. Expressed in terms of ppm in the feed.

MRL: The concentration of a chemical residue, in units of mg/kg, that is legally permitted in or on a food or food commodity.

ppm in the feed: Parts per million in the feed. An alternate way of expressing the level of dietary exposure for a chemical. The level of chemical intake is calculated as though it were present uniformly in the total feed intake. The ppm in the feed is calculated using the following formula: DDIL (mg chemical/kg bw) _ body weight (kg) ¸ daily feed intake (kg).

 Attachment 1: Anticipated maximum dietary exposure

The following calculations outline the theoretical diet used to calculate the maximum anticipated dietary exposure, maximum feeding level (MFL) and the daily dietary intake for livestock (DDIL) for cattle, sheep, pigs and poultry.
