Consultation on Putrescent Whole Egg Solids and its Associated End-use Products, Proposed Re-evaluation Decision PRVD2022-11

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of products containing putrescent whole egg solids registered for sale and use in Canada.

Putrescent whole egg solids is an outdoor animal repellent and feeding deterrent to protect a variety of non-edible plants, trees, and shrubs. A commercial-class product can be applied via handheld equipment, backpack sprayers, pressurized tanks, and spray boom on commercial sites – including nurseries, greenhouses, and forestry plantations. Domestic-class products can be applied using handheld and backpack sprayers or shaker duster (powder formula to deter deer, or as tulip bulb dip to repel squirrels.

Putrescent whole egg solids is a biopesticide with a non-toxic mode of action and has value in providing a pest management solution. Based on the current use pattern of putrescent whole eggs solids, dietary exposure is not anticipated. The potential risks to human health (occupational, residential, and bystander) and environment are considered acceptable when products containing putrescent whole egg solids are used according to the proposed label directions. Proposed label amendments include standard personal protective equipment requirements for workers, restricted entry into treated areas until sprays have dried, a standard drift statement, waterproof gloves for domestic class products, a warning statement to protect aquatic habitats on all product labels, and additional label updates to clarify use sites and use instructions.

For a full list of products containing putrescent whole egg solids, 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”.
