Poultry

Water parks

Petting zoos

Carrots

Answer and Explanation

The Correct Answer is C

A. Poultry: Poultry is more commonly associated with Salmonella and Campylobacter infections rather than E. coli 0157:H7.

B. Water parks: While waterborne outbreaks can occur, direct animal contact is a greater risk factor for E. coli 0157:H7 infection.

C. Petting zoos: Petting zoos pose a significant risk because E. coli 0157:H7 can be transmitted through contact with infected animals and their feces. Children and immunocompromised individuals are especially vulnerable.

D. Carrots: While contaminated produce has been linked to E. coli outbreaks, petting zoos pose a higher risk due to direct exposure to infected animals.

Correct Answer is B

Explanation

A. Allow patients to refuse medications: While patients generally have the right to refuse treatment, public health laws can override this right in cases of communicable diseases to protect public safety.

B. Place someone on house arrest for not being compliant with their TB medication: Under public health laws, states have the authority to enforce quarantine or isolation to prevent the spread of infectious diseases like tuberculosis (TB), especially if an individual refuses treatment.

C. Allow patients to have advance directives in place: Advance directives relate to personal healthcare decisions, not police power, which focuses on protecting public health and safety.

D. Arrest someone for using illegal drugs: While drug use is a legal issue, police power in public health is focused on disease control rather than criminal enforcement of drug laws.
