Opinion of the Scientific Panel on contaminants in the food chain [CONTAM] related to camphechlor as undesirable substance in animal feed

“…In cows exposed through the diet for 8 weeks to 20, 60, 100, and 140 mg camphechlor/kg of feed camphechlor transfer into milk was investigated. Levels in milk ranged from 0.2 to 1.4 mg/kg after one week and from 0.2 to 1.8 mg/kg after 8 weeks at the various exposure levels, showing a linear relationship between exposure and residue levels (Claborn et al, 1963).…”

“…Camphechlor was given to cows at 20, 60, 100, and 140 mg/kg feed for eight weeks in an experiment to investigate transfer to milk. There were no clinical signs of poisoning in any of the animals (Claborn et al, 1963). Lactating cows have a daily dry matter intake of about 4 % of body weight (Pond et al, 1995a).…”
