o:295 Cleaning efficiency of feed production lines after production of feedstuffs with coccidiostats en Intensive broiler production implies regular use of coccidiostats approved as feed additives. However, due to their chemical properties, coccidiostats can stay behind in the production line, and consequently, unavoidable cross-contamination of non-medicated feedstuffs can result in the exposure of non-target animal species and in the potential for coccidiostat residues in foods, such as chicken meat and eggs, derived from these species. In this way, coccidiostats enter the human food chain and can pose a health problem. The aim of this study was to determine the success of line cleaning after the application of salinomycin and maduramicin in feed. We tested the cleaning matrix (wheat groats) in order to demonstrate how many cleaning replicates are needed to safely produce coccidiostat-free feedstuffs. After the application of salinomycin, it is recommended that, for safety reasons, the line be cleaned with at least five batches of wheat groats of 480 kg each. In the case of maduramicin, it is recommended the line be cleaned with a minimum of eight batches, considering the relatively low permissible level of maduramicin as a contaminant in medication-free feed 1552099 10.1088/1755-1315/854/1/012037 2022-05-19T10:09:21.606Z 44 yes 46 Saša Janković Institute of meat Hygiene and technology Cleaning efficiency of feed production lines after production of feedstuffs with coccidiostats 0000-0002-5223-6993 Tatjana Radičević Institute of Meat Hygiene and Technology Cleaning efficiency of feed production lines after production of feedstuffs with coccidiostats person Srđan Stefanović Institute of meat hygiene and technology Cleaning efficiency of feed production lines after production of feedstuffs with coccidiostats person Sanin Tanković Veterinary Office of Bosnia and Herzegovina, Ministry of Foreign Trade and Economic Relations, Marsala Tita 9a, Sarajevo, Bosnia and Herzegovina Cleaning efficiency of feed production lines after production of feedstuffs with coccidiostats person Jasna Đinović-Stojanović Instiute of meat hygiene and technology Cleaning efficiency of feed production lines after production of feedstuffs with coccidiostats person 0000-0003-4602-0835 Danka Spirić Institute of meat hygiene and technology Cleaning efficiency of feed production lines after production of feedstuffs with coccidiostats person 0000-0002-6008-7625 Dragica Nikolić Instiute of meat hygiene and technology person application/pdf 647618 https://unilib.phaidrabg.rs/o:295 no yes 16 70 92000004 71A01 IOP Conf.
