Method for the Detection of Zeranol and SOP : ARO/442 Taleranol In
TITLE: Method for the detection of zeranol and S.O.P. : ARO/442 taleranol in meat and liver Page : 1 of 9 . Revision : 0 Date : 990715 1. INTRODUCTION 1.1 Summary This SOP describes a screening and confirmation method for the determination of resorcyclic acid lactones (RAL’s) in meat and liver samples of bovine origin. A procedure is described for the detection of a-zearalanol (zeranol) and b-zearalanol (taleranol) by a combination of solid phase extraction (SPE) and GC-MS. The method consist of, digestion of the meat sample using the enzyme protease and hydrolysis of the liver sample using suc d’Helix Pomatia, extraction of the RAL’s with tert-butylmethylether (TBME), purification using reversed-phase C18 cartridges. This method can also be used for the metabolites a-zearalenol, b-zearalenol, zearalanone and zearalenone. When doing so validation for these compounds is necessary. 1.2 Field of application The method is used to perform routine screening in meat and liver samples and has proven to be suitable for the analysis of a-zearalanol and b-zearalanol. The limit of detection is 0.5 mg/g based on the detection of the most abundant diagnostic ions namely m/z 433 and m/z 437 for the internal standard, with a response at the correct retention time exceeding the signal to noise ratio of 3. The method is validated according to SOP ARO/425 (1.3.3). 1.3 References 1.3.1. H.J. van Rossum et al, Multi residue analysis anabolic agents, SOP ARO/113, revision 4, 21 January 1997, RIVM. -

The other annexes can be found in the following addenda: – Annex A: Add.1 – Annex B: Add.2 – Annex C: Add.3 – Annex E: Add.5 – Annex F: Add.6 – Annex G: Add.7 WT/DS320/R/Add.4 Page D-1 ANNEX D REPLIES OF THE SCIENTIFIC EXPERTS TO QUESTIONS POSED BY THE PANEL A. GENERAL DEFINITIONS 1. Please provide brief and basic definitions for the six hormones at issue (oestradiol-17β, progesterone, testosterone, trenbolone acetate, zeranol, and melengestrol acetate), indicating the source of the definition where applicable. Dr. Boisseau 1. Oestradiol-17β is the most active of the oestrogens hormone produced mainly by the developing follicle of the ovary in adult mammalian females but also by the adrenals and the testis. This 18-carbon steroid hormone is mainly administered as such or as benzoate ester alone (24 or 45 mg for cattle) or in combination (20 mg) with testosterone propionate (200 mg for heifers), progesterone (200 mg for heifers and steers) and trenbolone (200 mg and 40 mg oestradiol-17β for steers) by a subcutaneous implant to the base of the ear to improve body weight and feed conversion in cattle. The ear is discarded at slaughter. 2. Progesterone is a hormone produced primarily by the corpus luteum in the ovary of adult mammalian females. -

October 2005) The effect of zeolite clinoptilolite (CLIN) on some metabolic parameters in blood serum and haematological values in weaned piglets fed with increased levels of zearalenone (ZEN) was investigated over a 14-day period. The research involved four groups of weaned piglets aged 40 to 54 days. All groups were fed on fodder mixture for growing pigs containing 20% crude protein and 12.57 MJ ME/kg. The first control group (C1) received a concentrate mixture without added ZEN or mycotoxin adsorbent Min-a-Zel Plus®. The second control group (C2) was fed on fodder mixture containing 0.2% of modified clinoptilolite (Min-a-Zel Plus®; levels of zearalenone <5.1 ng/g). Piglets in the experimental group (E1) were fed on fodder mixture containing added zeralenone (3 mg/kg) (Sigma-Aldrich Co) and 0.2% of Min-a-Zel Plus® preparation. The second experimental group (E2) was fed on fodder mixture to which 3 mg/kg of zearalenone was added, but with no addition of Min-a-Zel Plus®. Oestrogenic effect of ZEN was evident in the sinergistic action with insulin which was manifested in an increased total protein level, lower level of glucose, triacylglycerols, serum iron, a higer level of cholesterol and higher aminotransaminase activity. -

014875 01 APP Mycotoxins in Cereals
APPLICATION NOTE Liquid Chromatography/ Mass Spectrometry Authors: PerkinElmer Applications Team PerkinElmer, Inc. Shelton, CT Determination of Mycotoxins in Cereals by LC-MS/MS Introduction Mycotoxins are toxic secondary with Online SPE metabolites produced by fungi, and are capable of causing disease and death in both humans and animals. As such, many countries and regions have regulations and applicable permissible limits in place for mycotoxin detection and identification (Table 1). Sample preparation is a critical step in the successful analysis of mycotoxins in food matrices. The “dilute and shoot” approach is a quick and easy way to introduce the sample into the LC/MS/MS analysis. However, due to the complexity of food matrices, this approach will often result in irreproducible matrix effects. Other sample prep techniques, such as offline solid phase extraction (SPE) and QUECHERS, require multiple time-consuming steps, and are prone to procedural and operator error. To overcome these problems and improve sensitivity, this work utilizes the addition of online solid phase extraction (SPE), coupled to an LC/MS/MS system for sample enrichment. This approach allows for significant and efficient analyte concentration, obviating the need for elaborate and time-consuming sample preparation procedures. Table 1.
