美国上次圆孢子虫疫情的元凶为树莓

   188bet滚球游戏 讯  据美国食品安全新闻网消息，美国卫生部门调查发现，17年前圆孢子虫疫情的元凶为进口自危地马拉的树莓。近年来美国、加拿大大量从中美洲国家危地马拉进口树莓，曾经引发大规模的疫情。

    部分原文报道如下：

    Seventeen years ago, an outbreak of the protozoan parasite cyclospora was quickly blamed on California strawberries - but these would later turn out not to be the source. What was missed in the investigation was the steady increase in imports of raspberries from the poor Central American nation of Guatemala.

    U.S. imports of raspberries from Guatemala were doubling every year and American consumers were literally gobbling them up when they arrived in the produce section every spring.
