"Food Poisoning" by Edwin O. Jordan is a scientific publication written in the early 20th century. The work serves as a comprehensive examination of foodborne illnesses, investigating various causes of food poisoning, including harmful bacteria and chemical contaminants, as well as the physiological effects these poisons have on people. Jordan holds a position at the University of Chicago, which lends authority to his exploration of the topic. At the start of the volume, the author outlines the prevalence of food poisoning and its significance as a public health issue, noting how many cases go unreported. He discusses the various types of food poisoning, such as those stemming from contaminated meats and unprocessed foods, and emphasizes the need for better investigatory methods to understand and prevent these occurrences. The early chapters also introduce the concept of food sensitization and allude to a range of deleterious substances that might contaminate the food supply, setting the stage for a deeper discussion into specific types of poisons and diseases associated with contaminated food.
