USDA APHIS is advising the public that it has prepared an environmental assessment concerning authorization to ship for the purpose of field testing, and then to field test, an unlicensed Fowl Laryngotracheitis-Marek's Disease Vaccine, Serotype 3, Live Marek's Disease Vector.

The environmental assessment, which is based on a risk analysis prepared for the field testing of this vaccine, examines the potential effects that field testing this veterinary vaccine could have on the quality of the human environment.

Based on the risk analysis, APHIS has reached a preliminary determination that field testing this veterinary vaccine will not have a significant impact on the quality of the human environment, and that an environmental impact statement need not be prepared.

APHIS intends to authorise shipment of this vaccine for field testing following the close of the comment period for this notice unless new substantial issues bearing on the effects of this action are brought to our attention.

It also intends to issue a US Veterinary Biological Product licence for this vaccine, provided the field test data support the conclusions of the environmental assessment and the issuance of a finding of no significant impact and the product meets all other requirements for licensing.

APHIS will consider all comments received on or before 8 April 2011. To find out more or submit comments online, click here.
