Which food group is often implicated in Shigella spp. outbreaks?

1. Milk and dairy products

2. Leafy greens

3. Raw poultry

4. Frozen fruits

The correct answer is: Leafy greens

Leafy greens are often implicated in Shigella spp. outbreaks due to their growth conditions and handling practices. Shigella bacteria can proliferate in environments where personal hygiene is compromised, such as in farming or food preparation settings where leafy greens are handled. These vegetables are frequently consumed raw in salads or sandwiches, which increases the potential for transmission if they are contaminated with Shigella. Additionally, leafy greens can be irrigated with contaminated water or handled by infected food workers who do not practice proper hygiene. Once contaminated, if not properly washed or cooked, they can transmit the bacteria to consumers, leading to outbreaks. While other food groups such as milk, raw poultry, and frozen fruits can be associated with various foodborne pathogens, leafy greens are particularly susceptible to Shigella due to these factors.
