USDA: Canadian firewood shipments require heat treatment
The U.S. Department of Agriculture's Animal and Plant Health Inspection Service requires heat treatment of shipments of all firewood made of hardwood species entering the United States from Canada.
The USDA is concerned about the increased spread of wood-eating pests, such as Asian longhorned beetle and emerald ash borer, within the United States.
Effective immediately, USDA will require all Canadian hardwood firewood be heat treated to a minimum temperature of 71.1' Centigrade for 75 minutes.
Commercial firewood shipments must also be accompanied by a treatment certificate issued by the treatment facility. Noncommercial shipments must include either a treatment certificate issued by the treatment facility or an attached treatment label, the USDA said.
