Question

which of the following methods is appropriate for communicating a consumer advisory about oysters served raw on the half shell at a catering event?
have servers verbally inform guests that the oysters are raw
put up a placard that states: \warning: raw food\
advise the host of the event about any risk of foodborne illness
provide table tents disclosing the items being served raw and associated health risks

Explanation:

When communicating a consumer advisory about raw oysters at a catering event, providing table tents that disclose the items being served raw and associated health risks is the most appropriate method. Verbal communication by servers may not reach all guests. A general "Warning: Raw food" placard is too vague. Advising the host alone does not directly inform the consumers (guests) who will be consuming the oysters. Table tents are a clear, visible, and direct way to inform each guest about the specific item (oysters) and its associated risks.

Answer:

Provide table tents disclosing the items being served raw and associated health risks.
