Japan will send two investigators to the Netherlands over the weekend to investigate allegations that a Dutch-made animal fat product may be the source of mad cow disease in Japan, Farm minister Tsutomu Takebe said Friday.

Takebe said the two will visit a Dutch factory Saturday where the animal fat in question was manufactured. They will remain in the Netherlands until next Saturday.

One of the experts is from the Agriculture, Forestry and Fisheries Ministry's livestock division and the other works at the Fertilizer and Feed Inspection Station, a public administrative body under the ministry's jurisdiction.
