RELATED: This One Thing Is Disappearing From Walmarts Nationwide. Grocery store sushi is often touch and go, but it may be even more so depending on where exactly you buy it from. The food website Mashed recently surveyed nearly 700 adults in the U.S. to find out their thoughts on the worst sushi sold at major grocery stores. According to their responses, Walmart was the worst place to satisfy your sushi craving, with nearly 55 percent of the votes. Kroger and Target fell next in line for the worst store-bought tuna rolls, but they only received 15 percent and 14 percent of the votes, respectively. In general, Walmart may not be the place to go if you’re planning on buying any type of seafood. A separate Mashed survey of nearly 600 U.S. adults found that around 33 percent of customers think the grocery store chain sells the worst quality seafood. A 2020 Reddit thread also had one insider from the grocery industry advising against Walmart’s seafood. “Walmart simply will only pay the lowest possible price regardless of the quality,” the Reddit user claimed. “The shrimp farms give their best product to people who pay for it and everything else goes to [Walmart].

Pay a little more and buy shrimp from better sources.” RELATED: If You Bought This at Walmart, Throw It Away Immediately, FDA Says.
