The Wall Street Journal has a story today on how hundreds of people around the USA are receiving packages in the mail with small unidentified seeds in them.
The packages are not labeled as containing seeds, but may say they have electrical parts or jewelry/beads in them. The packages appear to be coming from China, though the return address is invalid, some of them may be marked as coming from the UAE.
If you receive one, DO NOT plant them or just throw the package away, contact your state agricultural department. The USDA is trying to identify the contents.
