Determination of hen ’s egg white lysozyme in milk and cheese - Interlaboratory collaborative study

This article presents the results of an international collaborative study conducted to validate previous technical specifications for the measurement of lysozyme in cheese. The work proposes minor modifications to the method, which will be published as an international standard (ISO 27105|IDF 216) for the determination of hen's egg white lysozyme in milk and milk products by HPLC.

The method is suitable for measuring low levels of hen's egg white lysozyme with a quantification limit of 10 mg/kg. The repeatability is 8.4% (95% CI: 6.7–9.3%) and the reproducibility 34.7% (95% CI: 20.8–59.0%).

Bulletin of the IDF N° 475/2014 - Proceedings of the 4th Paratuberculosis Forum - Parma, Italy, 21 June 2014

This publication contains seventeen papers written by representatives of national and regional Johne’s disease control programmes on the lessons learnt through their implementation. The papers were presented and discussed at the 4th Paratuberculosis Forum in Parma, Italy, on the 21 June 2014 at the offices of the European Food Safety Authority and attended by participants from 16 countries. Presentations cover a variety of approaches to manage Johne’s disease, from compulsory regulations targeting clinical disease to voluntary industry programmes aimed at reducing economic impact and supporting the production of high quality milk. A common theme was the integration of various testing strategies with important hygiene measures to prevent new infections. The papers highlight the successes and challenges and the importance of communications and incentives to maintain farmer engagement and cooperation, in order to ensure Johne’s disease control programmes are more effective in the future. Keywords: Johne’s disease, paratuberculosis, MAP, disease control, testing strategies, hygiene measures

Detecting antibiotic residues in milk - Guidance on the application of screening and confirmatory methods in integrated dairy chain management.

This document describes a pragmatic way to implement the testing of antibiotic residues along the dairy chain. From the farm to the dairy processing factory, the various stages at which tests can be implemented are detailed. Checking compliance with regulations is the main reason for testing. Examples of different regulations in terms of residue limits are included. All the actors of the dairy chain are responsible for ensuring safe milk delivery. The document provides tools that can be implemented at any level of the dairy chain and can help in choosing the most suitable method. Sampling good practices, recommendations for sample storage, advantages and disadvantages of available methods and procedures applied to validate the tests are all discussed. The document ends with examples of applied strategies in different countries. Tables show regulated procedures and some pragmatic ways to ensure a safe milk supply. The reader will notice that testing should be implemented from the very beginning of the milk production chain to check the absence of contamination. Collaboration with the antibiotic prescribers to control the use of antibiotics and reduce the risks of contamination is a complementary approach to achieve the delivery of safe milk. Keywords: Antibiotic residues, Testing, Detection, Milk safety, Veterinary drugs, ADI, MRL, Screening methods, Confirmatory methods
