Marvin J. Bleiberg, 84, a retired Food and Drug Administration toxicologist, died Feb. 1 at his home at the Greenspring retirement community in Springfield.

He had complications from Parkinson’s disease, his son Lawrence Bleiberg said.

Dr. Bleiberg joined the FDA in the mid-1970s and specialized in the review of toxicological and pharmacological data related to food and color additives. He received an award for outstanding service before retiring in 2004 from the FDA’s Center for Food Safety and Applied Nutrition.

Marvin Jay Bleiberg was born in New York City and moved to Virginia as a teenager. He was a 1949 chemistry graduate of the College of William and Mary in Williamsburg, and he received a doctorate in pharmacology in 1957 from what is now Virginia Commonwealth University in Richmond.

His early career included part-time teaching at Howard University and employment with government contractors in Northern Virginia.

Dr. Bleiberg was a former president of the Association of Government Toxicologists, his son said, and he belonged to professional organizations including the American Chemical Society and the Society for Experimental Biology.

He lived for nearly four decades in Fairfax City, and he had belonged to Congregation Olam Tikvah since 1967. He moved to Greenspring in 2004.

Survivors include his wife of 53 years, Beulah Matt Bleiberg of Greenspring; two sons, Lawrence Bleiberg of Birmingham, Ala., and Robert Bleiberg of Grand Junction, Colo.; and two grandchildren.
