Veterinary Laboratory Investigation and Response Network (Vet-LIRN)

Biography

Dr. Renate Reimschuessel is the director of Vet-LIRN in FDA’s Center for Veterinary Medicine/ Office of Research. She obtained her VMD from the University of Pennsylvania’s School of Veterinary Medicine in 1981. Following graduation, she practiced small and exotic animal medicine for five years. In 1989, she received a PhD in pathology from the University of Maryland. Upon graduation, she became the director of the university’s Aquatic Pathobiology Center. In 1999, Dr. Reimschuessel came to the Office of Research at the Center for Veterinary Medicine (CVM), Food and Drug Administration (FDA), to develop the aquaculture research program. Dr. Reimschuessel was a finalist for the 2008 Service to America Awards for her investigation during the 2007 recall of pet food due to melamine adulteration of ingredients. Because of her work with the pet food industry and cooperative studies with veterinary diagnostic laboratories during the 2007 and 2008 melamine adulteration events, Dr. Reimschuessel was selected to serve as director a new program, the Veterinary Laboratory Investigation and Response Network (Vet-LIRN) in 2010. The Vet-LIRN Program Office (VPO), which is located at the Office of Research, fosters communication between FDA and veterinary diagnostic laboratories, shares information with network laboratories on feed/drug adverse events, organizes laboratory proficiency tests, and funds animal diagnostic testing to enable investigations of potential feed/drug-related issues.

Research

In late 2010, FDA initiated a program, the Veterinary Laboratory Investigation and Response Network (Vet-LIRN), to collaborate with veterinary diagnostic laboratories to build laboratory capacity for routine and emergency response. The overall goal for FDA is for 40 participating laboratories to be ready, willing, and able to help investigate potential problems with animal feed and animal drugs providing a rapid response to reports of animal injury. Recent activities include developing and validating new laboratory testing methods, investigating possible contamination events such as excess Vitamin D in animal feed, and exploring the potential relationship between Dilated Cardiomyopathy and certain grain free or high legume content pet foods.

Vet-LIRN laboratories are also participating in the national initiative to Combat Antibiotic Resistant Bacteria (CARB) by collecting veterinary pathogens for antimicrobial susceptibility testing and sequencing. This program has provided a wealth of information to FDA, with the ultimate goal of detecting emerging issues and of fostering antimicrobial stewardship in veterinary settings. 

The Network provides FDA with critical laboratory testing data from experts around the country, evaluating animal diagnostic samples (e.g., urine, blood, feces, saliva, liver, kidney, etc.) not the typical food matrices. Cooperative agreements fund the network and enable these laboratories to serve as first responders in case investigations and emergency response activities when the ability to quickly track down and isolate a dangerous pathogen or chemical adulterant is critical.
