Delays for FBS Safety Testing - Imports into the US
ISIA is aware of delays, dating back to mid-January 2025, for FBS safety testing for serum imported from geographies that require testing (Australia, Mexico, and Central America). The Association is in consistent contact with the National Veterinary Safety Lab (NVSL) and will communicate updates as they are received.
The delays stem from a lack of suitable animals for Blue Tongue Virus (BTV) testing, which can be due to several factors, such as the seasonal drop in available stock after the winter.
NVSL is committed to resolving these delays as quickly as possible, and ISIA will continue to keep the industry updated on progress and updates. Updates will be posted on the ISIA website and on the ISIA LinkedIn page.
