Wadsworth Center Laboratories Participate in Food Emergency Response Network (FERN) Exercise

Food Emergency Response Network (FERN) Exercise

Tuesday, December 27, 2016

FERN was formed in response to the anthrax attacks that followed 9/11. It was then and is now a network of local, state and federal laboratories which contributes testing capability and capacity, relieving the burden to other agencies that also test food samples. Over time, the mission of FERN has broadened to include food safety and public health emergency and outbreak testing.

Because food could be contaminated, intentionally or not, by many types of agents, there are FERN microbiology, chemical, and radiation laboratories. Wadsworth Center is home to all three.

The Many Ways Wadsworth Helps to Ensure Food Safety

Wadsworth Center is an Integrated Food Safety Center of Excellence and contributes to the following:

  • PulseNet-a database of bacterial DNA fingerprints that identifies outbreaks
  • CaliciNet-performs surveillance for norovirus.
  • NORS-National Outbreak Reporting System is an electronic method for public health departments to report outbreaks
  • FoodNet-Foodborne Disease Active Surveillance Network conducts surveillance for a variety of bacterial pathogens

Recently, Wadsworth Center’s FERN microbiology and chemical laboratories took part in a capacity and capability drill. These exercises challenge the laboratory’s ability to test a large number of samples, for a specific agent (pathogen, toxin or toxic chemical), in a given period of time. Both laboratories test the same samples. The FERN radiation laboratory participates in approximately three separate exercises each year.

The FERN microbiology laboratory is a level 1 laboratory funded through the USDA – developing methods, participating in proficiency testing (up to eight times per year) and training other member laboratories.

As a level 1 participant, funded through the FDA, the FERN chemistry laboratory also develops methods, prepares proficiency tests, which it distributes to other FERN members, and demonstrates competency by participating in proficiency testing through the FDA.

FERN laboratories respond to all food-related events in New York. In addition to food items, they have analyzed non-routine samples including water, drugs and solid materials for toxic chemicals and agents that can threaten the health of residents. At times, testing results have become central to criminal investigations.

A Network of Networks

The Department of Homeland Security coordinates 5 networks into one ICLN (Integrated Consortium of Laboratory Networks):

  • LRN-Laboratory Response Network
  • FERN-Food Emergency Response Network, coordinated by:
    • Health and Human Services (HHS) / Food and Drug Administration (FDA)
    • US Department of Agriculture (USDA) / Food Safety and Inspection Service (FSIS)
  • eLRN-Environmental Laboratory Response Network through the EPA
  • NAHLN-National Animal Health Laboratory Network in cooperation with the USDA
  • NPDN-National Plant Diagnostic Network through the USDA

Surveillance is another very important function of Wadsworth Center's FERN laboratories. For example, during the 2012 presidential conventions and the following inauguration, the laboratories tested various food samples. Wadsworth Center FERN laboratories tested samples prior to one of the 2016 presidential conventions, while other member laboratories tested samples from the other convention. The microbiology and chemistry laboratories perform surveillance quarterly, while the radiation laboratory reports monthly to FERN on testing performed.

In addition to surveillance to detect an event and testing samples during an event, FERN laboratories also test samples after an event – after a manufacturer has decontaminated and resumed processing for example - to verify the food supply is again safe.
