What are some signs and symptoms from a brief exposure to bromadiolone?

Bromadiolone is toxic to mammals. It prevents the body from recycling vitamin K which is needed to make the blood clot. Because the body has reserves of vitamin K, it may take a while to go through its supply. Therefore, symptoms may be delayed for up to 5 days after exposure and may not be noticed until immediately before death.

Signs of poisoning in dogs can include bleeding from the mouth and nose, internal bleeding, bruising, bloody urine and stool, hypothermia, depression, lack of appetite, muscle weakness and pain, difficulty breathing, seizures, coma, and death.

People who have eaten bromadiolone have experienced symptoms such as nose bleeds, bleeding gums, bloody urine, black tarry stools, and bruising. Other less commonly reported symptoms include headaches, sore throat, muscle aches, shortness of breath, abnormally heavy periods, and bloody mucus. Skin contact with bromadiolone can cause slight irritation. If it gets in the eyes, it can cause eye redness, swelling, and irritation.
