Nominally, the decision was made in response to various violations, including labeling the fish and miscalculated calorie amounts.
"Canned fish imports are halted effective August 1. As of now, it concerns four Latvian companies," said Popova. "We are continuing to evaluate the quality of other fish products," she added.
Popova said that the State sanitary service found a number of consumer rights laws had been violated, saying that there's "a whole spectrum" of different violations.
In early June, a number of fish canneries were subject to a similar ban when Russia prohibited imports of fish and fish produce from Latvia and Estonia, mainly hitting sprat producers.
