Antibiotics are such compounds that are used for prevention or treatment during the breeding term. The lack of attention of the farmers to veterinary recommendations regarding observance of the prohibition of slaughter and poultry consumption, increases the amount of residues in poultry meat. Regarding the complications caused of these residues, such as drug resistance of germs, increased sensitivity to consumers, etc. In the present study, antibiotics residues of different groups, including quinolones, macrolides and fluorophenicol were investigated. Totally 8 antibiotics (4 antibiotical classes) in muscle and liver tissues of 90 samples from 13 slaughterhouses and 13 separate herds in early 1397 with a systematic random probability were collected, By liquid chromatography with a tandem mass spectrometer according the Grabnelli and el al method tested in the Residues Department of National Diagnostic Center of IVO.Finally, form 21 analytes that just Lincomycinthe macrolide class, and the enrofloxacin, ciprofloxacin in Quinolines was detected in sample and most of the frequency belong to ENR, LINCO.CIP, STZ respectively, and this ratio is significantly correlated with both liver and chicken tissue matrix. It should be mentioned that in 24 and 16% of muscles and livers only one type of antibiotic was detected there aren’t any samples with more than one antibiotic. None of the positive amounts weren’t above ISIRI and EU MRLs, then again, the presence of antibiotics, in particular, can be a potential public health hazard.

Slaughterhouses are one of the most important sites for animal health monitoring and disease surveillances and implementation of control strategies. Valuable information about animal disease status can be achieved through routine meat inspection measures in slaughterhouses. urveillance and monitoring of various animal diseases and zoonoses such as Foot and Mouth Disease (FMD), tuberculosis, brucellosis, parasitic infections) like fascioliasis, cysticercosis, trichinosis(or and high risk diseases such as Bovine Spongiform Encephalopathy (BSE) (because of easy detection of downer cow syndrome) are easily possible through ante- and postmortem meat inspection in slaughterhouses. In 2016, a cross sectional study was conducted with the objective of land territorial planning for slaughterhouses in our country. The study was done by collecting available information from Iran Veterinary Organization Council and municipalities using questionnaire. According to our results, totally, there are 396 slaughterhouses including 336 traditional and 60 industrial slaughterhouses in our country. Also for achieving the desirable health situation, we need to build at least 3, 26, 56 and 31 industrial modern slaughterhouses on the basis of the four patterns suggested by Iran Veterinary Organization, respectively. In conclusion, when we plan for implementation of prevention and control strategies for animal diseases, land territory for building slaughterhouses is really an appropriate tool for reducing live animal transport and replacement of meat trade with live animal trade.
