Listeria monocytogenes infections are often transmitted through contaminated food. A person who has contracted listeriosis usually has a high fever, muscle aches, and gastrointestinal problems such as diarrhea. In severe cases meningitis can develop and the disease can be deadly. Refrigeration of food contaminated with this microbe does not prevent the transmission of the disease as the microbe can grow in refrigerator temperatures. How would you categorize Listeria based on its ability to grow in the refrigerator? Explain. Which temperature category would most pathogens fall into? Explain. Which temperature category or categories would you not expect to find any pathogen? Explain.
