Two more Ecuadorian shrimp companies have had their export approvals to China suspended.

According to an updated notice by China’s General Administration of Customs, shrimp from Expalsa and Congelados y Frescos will no longer be permitted entry into China.

The suspension applies to Expalsa's Duran-based shrimp unit, located on Kilometer 6.5 via Duran Tambo, and Congelados y Frescos' unit, located on vía Panamericana Km 1 1/2 Entrada a Huaquillas. Expalsa is Ecuador's second-largest shrimp exporter.

Shipments dispatched from Ecuador after Sept. 11 will be prevented from entry to China.

The suspension was enacted after the positive detection of infectious subcutaneous and hematopoietic necrosis virus in the two companies’ shrimp products, the notice states.

Five Ecuadorean shrimp exporters have now been hit with suspensions; Industrial Pesquera Santa Priscila, Omarsa, and Winrep were hit earlier this week.

The suspensions were listed under Chinese custom's List of Fishery Products Establishments Registered to P.R China, described as being updated on Sept. 6.

Chinese media have been predicting that the suspensions will have a major impact on available shrimp supply.

Seafood Guide, a Chinese industry publication, estimates Chinese importers placed orders for over 1,000 containers of shrimp in the period two business units of Ecuadorean firms Omarsa and Santa Priscila were officially suspended from exporting to China.

In total, "orders for 1,100 containers of shrimp” were placed with Omarsa between Aug. 5 to Sept. 6 and with Santa Priscila between Aug. 23 to Sept. 6, it said, citing industry sources.

The periods refer to the start of retrospective suspensions for both firms and their announcement by China’s General Administration of Customs.
