Chinese authorities in Chongqing detected new COVID-19 cases on the outer packaging of frozen Ecuadorian shrimp.

This comes days after three Ecuadorian shrimp producers Industrial Pesquera Santa Priscila SA, Empacreci SA and Empacadora Del Pacifico Sociedad Anonima Edpacif were banned from importing products to China over coronavirus links.

Shapingba district in Chongqing released a statement on Wednesday that some of the packaging samples from Ecuador shrimp in a local logistic park tested positive for novel coronavirus, according to the news site China Daily.
