Listeria monocytogenes is identified as which of the following?

  1. Bacteria

  2. Protein

  3. Enzyme

  4. Acid

The correct answer is: Bacteria

Listeria monocytogenes is classified as a type of bacteria. This organism is a rod-shaped, gram-positive bacterium known for its ability to survive and grow in various environments, including refrigeration. It is notably associated with foodborne illnesses, and it can cause listeriosis, a serious infection primarily affecting pregnant women, newborns, the elderly, and individuals with weakened immune systems. Understanding that Listeria monocytogenes is a bacterium is crucial for food safety, as it highlights the importance of proper food handling and hygiene practices to prevent contamination and promote public health. The other options—protein, enzyme, and acid—do not accurately describe Listeria monocytogenes, as they refer to different categories of biological entities or molecules. This distinction is vital for addressing concerns related to foodborne pathogens and their implications in dairy and other food products.
