Consultation on Dried Blood and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2021-11

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of products containing dried blood registered for sale and use in Canada, provided the proposed updates to label directions are in place.

Dried blood is an outdoor animal repellent used against deer, elk, hares and rabbits to prevent damage caused by feeding or browsing to established and seedling conifers, as well as outdoor ornamentals. Dried blood is a biological substance with a non-toxic mode of action and has value in providing a pest management solution. Based on the current use pattern, risks are considered to be acceptable when products containing dried blood are used according to label directions. As a result of re-evaluation, no additional mitigation measures are proposed; however, updates to standard label statements to meet current labelling standards are proposed.

For a full list of products containing dried blood, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.

For more information on the proposed decision open the "Proposed Re-evaluation Decision".
