Final answer:
Young children are at higher risk for foodborne illness because their immune systems are not fully developed, they often have poorer hygiene habits, and they are more susceptible to severe symptoms due to their smaller size and developing organs. The correct answer is option B
Step-by-step explanation:
Young children are at a higher risk for foodborne illness primarily because their immune systems are not yet fully developed. This makes them less capable of fighting off infections compared to adults. Infants and young children have not been exposed to a wide range of pathogens to build a strong immunological memory, which is critical in protecting them against diseases. Moreover, due to their smaller size and developing organs, young children can experience more severe symptoms and complications from foodborne illnesses.
It's also essential to note that certain foods, like honey, can contain bacteria that cause diseases such as infant botulism, which is why it's advised not to feed honey to children less than 12 months old. Following good food safety practices, including proper handling, preparation, and storage of food, can significantly reduce the risk of foodborne illnesses.
