Tridge summary

A agricultural cooperative in Vietnam has identified red sacks and double-layer drying tarpaulins as the source of sudan contamination in two batches of exported black pepper, leading to their return by Taiwan. Tests by Eurofins Sac Ky Hai Dang Company Limited revealed high levels of sudan III and IV in the sacks and trace amounts in the tarpaulins, exceeding the Taiwanese maximum residue limit.

This incident underscores the need for stricter regulations on packaging materials to prevent sudan contamination in pepper and maintain its market reputation.
