The U.S. Department of Agriculture has published notice of a pest risk assessment for importation of fresh lychee from South Africa.

According to the Federal Register, the USDA believes that designated phytosanitary measures for South African fresh lychee — either methyl bromide fumigation or irradiation — will be adequate to prevent the threat of introducing new pests to the U.S.

The proposal is available for review and comment through April 4.

South Africa produces about 6,272 tons of lychee, and exports about 2,240 tons to Europe, according to the USDA. The department said volume from South Africa to the U.S. is estimated to be more than 100 containers.

Irradiation treatment is used for lychee from Hawaii, China, India, Israel and Taiwan, according to the USDA.
