A foodborne bacterial ailment called listeria infection may be highly dangerous for pregnant women, individuals over 65, and those with compromised immune systems. It is generally brought on by ingesting deli meats that have not been properly handled and unpasteurized milk products. Healthy individuals seldom become sick from listeria infections, but the sickness can be fatal for new-borns, unborn infants, and adults with weakened immune systems. With timely antibiotic treatment, listeria symptoms can be reduced. Both freezing and refrigeration are ineffective against Listeria bacteria. Although a listeria infection is likely to impact a pregnant woman, the signs and symptoms it causes are usually mild. The results for the baby, however, might be disastrous; the infant may pass away in the womb or get a potentially fatal infection within a few days after birth. The modest signs and symptoms of listeria infection in a baby might include: Little appetite, irritability, fever, vomiting, and breathing difficulties. Most listeria infections are undetectable because they are so mild. A listeria infection, however, can occasionally result in life-threatening side effects, such as generalised blood infection and inflammation of the membranes and fluid around the brain (meningitis). Simple food safety recommendations should be followed to avoid contracting listeria: Maintain cleanliness:  Before handling or preparing food, as well as afterward, thoroughly wash your hands with warm, soapy water. After cooking, wash the utensils, cutting boards, and other surfaces used for food preparation with hot, soapy water. Scrub uncooked veggies:  Utilizing a scrub brush or vegetable brush and lots of flowing water, clean raw veggies. Cook your meal to perfection: Make sure your meat, poultry, and egg dishes are cooked to a safe temperature by using a food thermometer.
