Agencies issue guidelines for eating fish from floodwaters


State agencies in Mississippi are working tirelessly to meet the challenges posed by the historic flooding of the Mississippi River, its tributaries and backwaters. Hundreds of communities and thousands of Mississippians are being affected now, and the effects of the flood will be felt long after the water recedes.

The top priority in this natural disaster is keeping people safe, and a key issue is the safety of eating fish caught in floodwaters. Last Friday, state chemist Kevin Armbrust at the Mississippi State Chemical Laboratory at Mississippi State University personally received six calls from folks asking if it was safe to eat fish out of flooded waters.

It is a critical question in areas where residents supplement their diets with fresh-caught fish.

Armbrust reports that the lab worked closely with the Mississippi Department of Environmental Quality and the Mississippi State Department of Health on guidelines to consider when consuming fish out of floodwaters. The Mississippi Emergency Management Agency released that information late last week:

While there is no data showing that fish from the floodwaters are unsafe to eat, people should use common sense and observe the following precautions:

- Don't eat fish or crawfish that come out of an oil, gas or diesel slick.

- Don't eat fish or crawfish that don’t look normal. For example, fish with sores, tumors, or discoloration.

- Don’t eat fish or crawfish that don’t act normally. For example, fish that are gasping for breath at the surface, swimming erratically, or that are dead or dying.

- Don’t eat fish or crawfish that smell unusual--such as sewage, diesel or chemical odor.

- If they taste funny, throw them out.

- Handle fish and crawfish from floodwaters carefully. Avoid hand to mouth, nose or eye contact and wash hands thoroughly after handling uncooked fish or crawfish from flooded areas.

- Cook fish and crawfish thoroughly to kill any bacteria that may be present.

And MEMA also advises anyone thinking about fishing in floodwaters to be aware of several issues:

- In response to Executive Order 1053 issued by Gov. Haley Barbour, the Mississippi Department of Wildlife, Fisheries, and Parks has closed all boating activity in counties affected by the recent flooding including: Adams, Bolivar, Claiborne, Coahoma, DeSoto, Jefferson, Humphreys, Issaquena, Sharkey, Tunica, Warren, Washington, Wilkinson, and Yazoo. This area will be expanded as needed.

- Floodwaters may have strong currents and unseen hazards under the surface of the water.

- Floodwaters often have high levels of bacteria as a result of flooded sewage systems and the decay of plant and animals that have been killed during the flood.

- Floodwaters may contain oil, gas, diesel, fertilizers or other chemicals.

MEMA’s best advice? It’s pretty simple: The safest thing to do is to avoid the flooded areas.

Public forums for MSCL director candidates set


After a nationwide search, the Office of Research and Economic Development at Mississippi State University will host three finalists for the position of director of the Mississippi State Chemical Laboratory and state chemist.

During their visits to Starkville, each candidate will deliver a public presentation. Interested members of the campus community are invited to attend these sessions.

The three candidates are:

Bert Lynn, who is currently director of the University of Kentucky Mass Spectrometry Facility and professor of chemistry. He holds a Ph.D. in analytical chemistry from Mississippi State University. Lynn’s presentation takes place Aug. 13 from 11 a.m. to noon in Colvard Student Union’s Fowlkes Auditorium.

Ashli Brown, who is currently director of research and agricultural forensics at the Mississippi State Chemical Laboratory and an assistant professor in the Department of Biochemistry, Molecular Biology, Entomology and Plant Pathology at MSU. She holds a Ph.D. in chemistry/biochemistry from the University of South Florida. Brown’s presentation takes place Aug. 14 from 11 a.m. to noon in Fowlkes Auditorium at Colvard Student Union.

Susie Dai, who is currently research assistant professor with the Office of the Texas State Chemist and Department of Veterinary Pathobiology at Texas A&M University. She holds a Ph.D. in chemistry from Duke University. Dai’s presentation takes place Aug. 15 from 11 a.m. to noon in Mitchell Memorial Library’s John Grisham Room.

Kevin Armbrust, who served previously as state chemist and MSCL director, joined the School of the Coast and Environment at Louisiana State University in July.
