“搀假货”常见的英文表达是 “adulterated goods” 或 “counterfeit/fake goods with adulterated content”。
“adulterated” 指在产品中掺入劣质或廉价物质，使其质量下降，常用于食品、药品等领域。例如：The authorities cracked down on the sale of adulterated milk powder.（当局严厉打击销售掺假奶粉的行为。）
“counterfeit/fake goods” 更侧重于假冒伪劣商品，若强调商品本身掺假，可加上 “with adulterated content” 进一步说明。例如：Selling counterfeit goods with adulterated content is a serious violation of the law.（销售掺假的假冒伪劣商品是严重的违法行为。）
