An acute rodenticide is described as requiring which feeding pattern?

• A. Requires single feeding in a short time frame
• B. Requires multiple feedings over days
• C. Acts slowly over weeks
• D. Works only when ingested with water

Answer: (A)

Acute rodenticides are defined by a rapid onset after exposure, meaning a lethal dose can be reached from a single meal. They act quickly once eaten, often within hours, so one feeding in a short time frame is enough to cause death. This contrasts with chronic rodenticides or anticoagulants, which require multiple feedings over days to accumulate a lethal dose. An ingestion that only works when mixed with water isn’t a defining trait for acute agents. For example, zinc phosphide can cause rapid death after a single meal.
