What contaminant is the primary agent of concern from ready-to-eat meal and poultry products?

The primary contaminant of concern from ready-to-eat meal and poultry products is Listeria monocytogenes. This bacterium is particularly dangerous because it can grow at refrigeration temperatures, allowing it to survive in environments where other pathogens might not. This characteristic makes Listeria a significant risk in ready-to-eat foods, which are often consumed without further cooking. Listeria can lead to severe health outcomes, especially in vulnerable populations such as the elderly, pregnant women, newborns, and individuals with weakened immune systems.

Furthermore, Listeria is capable of causing listeriosis, an infection that can result in severe complications, including meningitis and septicemia. The concern with poultry products arises from potential cross-contamination during processing, handling, and storage, highlighting the importance of safe food practices. Understanding the risks associated with Listeria is crucial for those involved in food safety, nutrition, and gerontological care given the heightened sensitivity of older adults to foodborne illnesses.
