Taiwan turned back two shipments of Japanese melons for excessive pesticide levels, bad news for the importer and a small headache for Japan's fruit exporters.

• Both melon shipments tested above the legal limit for a pesticide, and 332 kilograms were sent back or destroyed.
• Both came from the same New Taipei importer, Chuan Yong Fruit, which has now failed three checks in six months.
• That company's future melon shipments face full inspection, and Japanese melons in general stay under heavy sampling into mid-September.
• Regulators also flagged frozen shrimp from Vietnam, tamarind sauce from Thailand, and a Japanese seaweed product carrying too much arsenic.

Outlook: Tighter border checks on Japanese produce will stay in place through September, and repeat offenders face inspection on every batch.
