Assembly bill steps up war against rat poison

A new bill that expands the prohibition of pesticide poisons in California passed the Assembly on Monday, days after the National Park Service announced a local mountain lion died in March due to ingestion of rat poison.

Assembly Bill 1788, introduced by Assemblymember Richard Bloom (D-Santa Monica) bans the use of second generation anticoagulant rodenticides, which are used in rat poison.

The second-generation poisons are considered far more potent than the first-generation compounds, and a lethal dose can be ingested in a single feeding.

Rat poison has come under fire because animals higher in the food chain, such as coyotes and cougars, eat the rodents that have ingested the fatal poison.
