19. Provide supplemental information here

Would not expect fatal outcome related to the product without showing any sign of pyrethroid toxicity. This produt has a wide margin of safety and is of topical action. The calf received topically 0.4 mg active ingredient per kg body weight. The oral LD 50 is 500 mg/kg bw. The calf had a concomitant medical condition that most likely was the cause of his demise, particularly considering the high fever and ongoing abscess. Although no necropsy was performed a product relation can be excluded.
