Final answer:
The question refers to the potential for food items marked with an asterisk to contain raw or undercooked ingredients, which can pose a health risk due to possible contamination with harmful bacteria.
Step-by-step explanation:
Items marked with an asterisk (*) may contain raw or undercooked ingredients.
When certain foods are handled by people and not cooked to a temperature high enough to kill harmful bacteria, like in the case of sliced meat, puddings, pastries, and sandwiches, this can pose a health risk.
It is important to note that raw or undercooked items, such as ground beef, milk and juice, vegetables like lettuce, and raw sprouts, can become contaminated.
Consuming raw (unpasteurized) milk and cheeses made from it, as well as other raw foods, increases the risk of foodborne illness, particularly when they come from facilities that also handle allergens such as gluten, milk, soya, and their derivatives.
