Doctors explain that Listeria infections often begin with mild symptoms such as fever, muscle aches, nausea, or fatigue. Because these early signs resemble common illnesses, many people ignore them. In vulnerable individuals, however, the bacteria can spread through the bloodstream and reach the central nervous system, potentially causing meningitis or severe neurological complications.
Older adults are particularly susceptible to these infections. As people age, their immune systems become less effective at fighting certain pathogens. Individuals with diabetes, cancer, kidney disease, or weakened immune systems face even greater risks. Health professionals emphasize that what might be a mild illness in one person can become a medical emergency in another.
Food safety experts say one of the biggest misconceptions is that cold storage automatically guarantees safety. In reality, bacteria can survive and sometimes multiply when food is stored improperly. Leaving leftovers in the refrigerator for too many days, failing to maintain the correct temperature, or using unclean containers can all increase contamination risks.
Specialists recommend consuming most cooked leftovers within three to four days. Foods that develop unusual odors, textures, or colors should be discarded immediately. Refrigerators should also be cleaned regularly to prevent cross-contamination between different food items.
Another important safety measure is proper reheating. Leftovers should be heated thoroughly before consumption to reduce bacterial risks. Experts also advise separating raw meat from ready-to-eat foods to prevent harmful microorganisms from spreading throughout the refrigerator.
