Verified step by step guidance

1. Step 1: Understand the context of the problem, which is about health risks associated with working with mice in a laboratory setting.
2. Step 2: Review each statement carefully to determine if it is true or false based on microbiological and occupational health knowledge.
3. Step 3: Recall that mice can transmit zoonotic diseases such as lymphocytic choriomeningitis virus (LCMV) to humans, so that statement is true.
4. Step 4: Recognize that bites and scratches from mice can introduce bacteria and cause infections, making that statement true as well.
5. Step 5: Know that allergic reactions to mice (such as allergies to mouse dander, urine, or saliva) are a well-documented risk in laboratory settings, so the statement claiming no risk of allergic reactions is false.
