Quality Management Practices of Gene Banks for Livestock: A Global Review.

The genetic diversity of livestock is decreasing and many countries have created gene banks for ex situ-in vitro conservation of animal genetic resources (AnGR). The collection, processing, and storage of animal germplasm require substantial investment and the material collected (and associated data) is highly valuable. Therefore, quality management systems (QMSs) and practices are important. The objective of this study was to review the quality management procedures of livestock gene banks around the world to identify the general strengths and weaknesses of quality control. A survey was administered by means of an online questionnaire consisting of 54 questions, most of which were yes/no with respect to the presence of a particular aspect of quality management. The survey was distributed through networks of the Food and Agriculture Organization of the United Nations that are associated with AnGR. Ninety responses were received from 62 countries. The gene banks were predominantly public institutions, with the main goal of preventing breed extinction. Approximately 30% of the banks reported having a QMS, 15 of which involved formal certification. Many other banks have plans to implement formal quality management within the next 5 years. Regarding specific aspects of quality management, more emphasis was placed on material entering the banks than on eventual utilization. Among the banks processing and freezing material, 90% followed specific standard operating procedures, but only 24% had policies regarding provision of access to external stakeholders. Increased cooperation among livestock gene banks could improve quality management. Sharing of knowledge could standardize procedures and cooperating peers could evaluate each other's QMSs.

Andra Environmental Specimen Bank: archiving the environmental chemical quality for long-term monitoring.

Andra Environmental Specimen Bank (ESB) was established in 2010 as a part of the Perennial Observatory of the Environment (OPE), ongoing Long-Term Environmental Research Monitoring and Testing System located next to the Underground Research Laboratory (URL) at Bure, Meuse/Haute-Marne, France. The URL is used to study the deep geological disposal of high and intermediate level radioactive waste. Andra ESB is designed to archive during at least 100 years samples collected to define the initial state of environmental quality of the local area before the construction of industrial facilities and to ensure the traceability of long-term series of samples collected by the OPE ( http://www.andra.fr/ope ), using safe long-term conservation practices. Samples archived in the bank include some local food chain products (milk, cheese, honey, cereals, grass, cherry plum…) and specimen usually archived internationally to monitor the environmental quality (soil, sediment, water, fish, tree leaves, wild life, etc.). Regarding the different samples and analytical issues, three conservation modalities and facilities were designed: dry conservation under controlled temperature and humidity, cryopreservation in liquid nitrogen (LN2) vapor phase freezers (-150 °C) and in deep-freezing at -80 °C for temporary storage and raw samples before preparation. Andra ESB is equipped with a sample preparation clean room, certified ISO Class 5, dedicated to cryopreservation. This paper describes this first French experiment of long-term chemical quality monitoring and samples cryopreservation of different ecosystems and environmental compartments.
