China's health commission in the city of Yunnan detected three new COVID-19 positive traces linked to the outer packaging of Ecuadorian white shrimp on Thursday.

The province's health commission collected a total of 2,750 samples of the South American shrimp to test for COVID-19 after the country banned three Ecuadorian shrimp producers on July 10 upon discovering traces of the virus.

The positive samples were produced by Santa Priscila -- one of the three banned producers -- with the batch numbers 3380, 3277 and 2616. However, the shrimp itself did not test positive.

Pingxiang, Jiangxi, Shaoyang, Hunan, Zheijiang and Guangdong provinces also launched similar investigations, however, no cases have been reported.

The new cases come only a few hours after Chinese authorities in Chongqing detected a new COVID-19 case on the outer packaging of frozen Ecuadorian shrimp.

Ecuador has been implementing efforts to rectify the current shrimp import saga. On Tuesday the Ambassador to the United Nations Luis Gallegos claimed the problem the country has been facing in regards to shrimp exports to China, was resolved.
