IETS Health and Safety Advisory Committee Pre-Conference Symposium

Monday, January 16, 2023
Co-Chairs: George Perry and Marc-André Sirard

Media news or new media—
How safe are in vitro-produced embryos for international trade?

Already, especially for cattle, global production of in vitro-produced (IVP) embryos exceeds collection of in vivo-derived (IVD) embryos.

Yet only a handful of countries have shown willingness to import livestock IVP embryos by developing import conditions for sanitary trade in these embryos. Some countries still have outdated regulations preventing importation of IVP embryos. In addition, many of the existing import conditions are now outdated, being based on research performed when co-culture cells and serum were the norm for culturing IVP embryos.

Recent technological developments have resulted in significant changes to the way oocytes are commercially processed to IVP embryos. Unfortunately, there is no published research into how this affects the risk of infection with and transmission of pathogens.

Many livestock breeders are now recognizing the vast improvements and advantages that IVP embryos bring to their breeding herds and to animal production. This daylong symposium is designed to provide researchers, practitioners, and regulators with the latest information on how the sanitary status of IVP embryos of cattle, small ruminants, and horses has improved to the extent that IVP embryos are now deemed by many experts to be safer from a sanitary perspective than IVD embryos.

We look forward to your attendance at this very important symposium. For those who cannot travel to Lima, Peru, there will be provision for a virtual conference. Accommodations can be booked at the Westin Lima Hotel and Convention Center, where the symposium will be held.
