EFFICIENCY OF LINE CLEANING METHODOLOGIES FOR ANIMAL FOOD PRODUCTION AFTER USE OF VETERINARY MEDICINAL PRODUCTS
Medicated feeds; carry-over; antimicrobial resistance; line cleaning
The increase in the competitiveness of the agricultural sector due to globalization has led to the need to increase the productivity of the livestock chain. For this, the stocking rate was increased, causing an increase in the occurrence frequency of diseases in the animals. In this way, the intense use of veterinary drugs, either preventively or therapeutically, has been practiced. Usually medicines are inserted into feed for animals on the same production lines where unmedicated feed is produced, thereby causing residual contamination, called carry-over. The occurrence of carry-over can cause drug residues in products of animal origin, as well as being a source of development of antimicrobial resistance by bacteria. Therefore, in addition to economic importance, its study is of fundamental interest to guarantee animal and population health. This study aims to verify the efficiency of line cleanings in feed manufacturers, analyzing the existence of active principles in medicated and non medicated rations manufactured in sequence.
