某女性公务员，30岁，已婚。对食品安全问题不放心4个月，伴反复检查、苦恼2个月。具体表现为：不敢在外边的饭店吃饭，担心饭店的菜洗不干净，炒菜用的油是泔水。不敢吃牛肉干，害怕得疯牛病，不敢吃猪肉，猪饲料中激素太多。尤其是“福寿螺”事件后，不仅小龙虾之类，甚至海鲜类的食物也拒绝吃了。米饭也是尽可能少吃，因为大米上的农药实在是太多了。该女士认为吃饭实在是令人头痛的事，导致进食量越来越少，体重明显下降，丈夫非常担心其身体差，不能孕育一个健康的孩子。因而，每天监督她进食，遭到她的强烈反对，为此二人经常争吵。近2个月来开始担心自己家的煤气没关好，每次不管出门还是晚上睡觉前都需要反复检查，为此经常上班迟到，感觉非常辛苦，也想控制不检查那么多次，但又不放心。
