In this survey aflatoxin, M₁ was quantified in raw and processed milk from various areas of two big cities of Punjab province, i.e. Lahore and Multan. The results indicated that approximately 90% of the raw milk samples collected from Lahore city was contaminated with aflatoxin M₁. Similarly, around 92% of the raw milk samples collected from Multan city was contaminated with aflatoxin M₁. All samples of processed milk and tea whiteners were contaminated and 56% of the contaminated processed milk samples and 66% of the contaminated tea whitener samples were violating the maximum limits. The dietary exposure data of AFM₁ among six different groups was calculated, which indicated that the male children population was the most vulnerable group to AFM₁, up to 6.68 ng L⁻¹ per day and the least affected one was the female group above 20 years of age with 1.13 ng L⁻¹ per day.

在本次调查中，黄曲霉毒素的定量方法是对来自旁遮普省两个大城市拉合尔和木尔坦的不同地区的原乳和加工乳中的M ₁进行定量。结果表明，从拉合尔市收集的大约90％的原奶样品被黄曲霉毒素M ₁污染。同样，从木尔坦市收集的大约92％的原奶样品被黄曲霉毒素M ₁污染。所有加工过的牛奶和茶增白剂样品均被污染，其中56％的污染过的加工牛奶样品和66％的污染的茶增白剂样品均超出最大限量。AFM ₁的饮食暴露数据计算了六个不同的群体，这表明，男性儿童是最易受AFM ₁影响的群体，每天高达6.68 ng L ^-1，受影响最小的是年龄在20岁以上的女性群体，年龄为1.13 ng L每天^-1。
