Australian lobster tails, imported as a premium product, have flooded the Vietnamese market at surprisingly low prices, raising concerns about their quality. Despite the cheap price, they are advertised as fresh and firm due to the way they are caught and frozen. However, a seller discovered that the meat's firmness and taste varied, leading her to stop selling them. The origin and food safety of the lobster tails are well-documented, but their low price and the possibility of being defective or nearing expiration suggest that they may not meet the expected quality. The owner of a seafood store also highlighted the potential for selling defective or expiring seafood as frozen, advising consumers to be cautious when purchasing unusually cheap seafood.
