Women’s Role in Reforming Food Safety

Innovators

Effie Alberta Read, PhD, assistant chief of the micro-analytical lab at FDA’s Bureau of Chemistry.

Before U.S. women earned the right to vote in 1920, three female pioneers in food safety endured discrimination to make major contributions to the field. In the 19th century, Amanda Theodosia Jones (1835-1914) came up with the standard for vacuum canning. Effie Alberta Read, PhD, (1871 est.-1930) quietly spent two decades developing micro-chemical procedures to detect adulterated products, work that became crucial for enforcing the first comprehensive U.S. consumer protection law—the 1906 Food and Drugs Act. And later on, Mary Engle Pennington, PhD, (1872-1952) became the first female lab chief at the U.S. FDA, conducting research to make the food supply safer and fresher.

Jones had a penchant for science, but let spiritualism guide her decisions. In 1872, she reportedly received a message from the spirits to write to Professor LeRoy Cooley of Albany, N.Y., who she knew through her sister. The spirits further told her canning could be done in a better way by removing the air in the container. Though she had no prior experience with canning, she and Prof. Cooley were able to collaborate to create the “Jones Method,” also known as the “Pure Food Vacuum Preserving Process(es).” They created the first model in 1873 and were granted five patents to cover the process, two of which were issued to her alone. The method became the standard for canning in the U.S. Jones discovered their method added more flavor to the food, but didn’t remove any nutritional value. It killed bacteria by lack of oxygen instead of just heat.

She also founded the Women’s Canning and Preserving Co. in 1890, but was unable to make a commercial success of it. The company, based in Chicago, employed only women, reportedly the first company to do so. It later was taken over by men after it was apparently unable to sell enough products because it was women-owned and run. Jones continued to invent and in 1906 came up with a vacuum process for drying food. She also created the first automatic safety oil burner, for which she also received a patent.

Dr. Read and Dr. Pennington also experienced gender discrimination, even as they contributed to food safety. Dr. Read earned both a PhD from Cornell University and MD from George Washington University. In acknowledging her contributions during Women’s History Month, the FDA noted that she was among the best trained analysts when she joined the agency’s Bureau of Chemistry in 1907.
