Core Insights - The article discusses the risks associated with consuming fruits stored in refrigerators during summer, particularly focusing on Listeria monocytogenes, which poses a significant threat to vulnerable populations such as pregnant women, the elderly, and young children [3][4]. Group 1: Food Safety Risks - Listeria monocytogenes is a major concern for pregnant women, as it can lead to severe health consequences [3]. - The bacterium is resilient in low-temperature environments, making refrigerated foods a potential source of infection [3]. - Fruits and vegetables can carry Listeria due to contact with contaminated water and soil during growth [3]. Group 2: High-Risk Foods - Certain foods, including cold dishes, unpackaged cooked meats, and some frozen products from small manufacturers, are identified as high-risk for Listeria contamination [3]. - The summer and autumn seasons are particularly prone to foodborne illnesses, with the World Health Organization reporting 420,000 deaths annually from such diseases [4]. Group 3: Prevention Measures - Key food safety practices include maintaining cleanliness, using safe water and ingredients, separating raw and cooked foods, cooking thoroughly, and keeping food at safe temperatures [5]. - It is recommended to wash fruits thoroughly with running water and to consume whole fruits rather than pre-cut varieties to minimize risk [8]. - For vulnerable groups, it is advised to avoid high-risk foods and ensure proper food handling and storage practices [3][8].
