📚 Understanding E. coli

Escherichia coli (E. coli) is a large and diverse group of bacteria. While most strains are harmless, some can cause serious illness.

📚 Understanding Listeria

Listeria monocytogenes is a bacterium that can cause listeriosis, a serious infection that primarily affects pregnant women, newborns, older adults, and people with weakened immune systems.

• 📅 Incubation Period: Symptoms can appear from 1 to 70 days after infection.
• 🤰 Symptoms: Fever, muscle aches, nausea, vomiting, and diarrhea. Can cause serious complications during pregnancy, including miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.
• 🌡️ Prevention: Avoid unpasteurized dairy products and ready-to-eat meats, heat leftovers thoroughly, keep refrigerator clean, and pay attention to "use by" dates.
