Investigation of Tetracycline Residues in Plain and Flavored UHT Milk on Sale

Abstract

In this study, tetracycline group antibiotic residue was investigated in plain and flavored UHT milk of different brands. A total of 90 UHT milk samples (62 plain and 28 flavored) were analyzed by ELISA method. Tetracycline residues were detected in all samples as a result of the analysis. The mean level of tetracycline was determined as 6.98±0.38 ppb in plain milk and 6.53±0.48 ppb in flavored milk. Residue levels in analyzed UHT milk were found to comply with the legal limits announced by the European Union (EU) commission and Turkish Food Codex Communiqué.

Sade ve Aromalı UHT Sütlerde Tetrasiklin Kalıntılarının Araştırılması

Abstract

Bu çalışmada, farklı markalara ait sade ve aromalı UHT sütlerde tetrasiklin grubu antibiyotik kalıntısı araştırıldı. Toplam 90 adet UHT süt örneği (62 sade, 28 aromalı) ELISA yöntemi ile analiz edildi. Analiz sonuçlarına tüm örneklerde tetrasiklin kalıntısı tespit edildi. Tetrasiklin ortalama düzeyi sade sütlerde 6,98±0,38 ppb, aromalı sütlerde 6,53±0,48 ppb olarak belirlendi. Analizi yapılan UHT sütlerdeki kalıntı seviyeleri Avrupa Birliği (AB) komisyonu ve Türk Gıda Kodeksi Tebliği tarafından açıklanan yasal limitlere uygun bulundu.
