A graduate of McGill University and the University of Toronto, Phyllis Entis received her introduction to the field of food safety at the hands of Canada's Health Protection Branch, where she spent the first seven years of her professional life immersed in Salmonella, Staphylococcus, E. coli and other bad actors from the microbial world.

After a long career in the food safety industry, Entis became a freelance consultant and writer. Her first book, Food Microbiology—The Laboratory, was published in 2002 by the Food Processors Institute. It was followed five years later by Food Safety: Old Habits, New Perspectives, which was released by the American Society for Microbiology Press in January 2007.
From 2008 onwards, Entis continued to write about human and pet food safety issues for several publications, including Food Safety News, The Bark, and her own food safety blog, eFoodAlert. She also found the time to write and release a six-book mystery series, The Damien Dickens Mysteries.

In 2020, she released TAINTED. From Farm Gate to Dinner Plate, Fifty Years of Food Safety Failures, updating the material presented in her 2007 food safety book.

With this year's release of TOXIC. From Factory to Food Bowl, Pet Food Is a Risky Business, Entis has achieved her long-standing goal of supplying pet owners with the information they need to understand the issues behind twenty years of pet food recalls and safety alerts.
