How Lactose Free Is Lactose-Free Milk?

I'm not absolutely sure why New York's Examiner.com website needs a "Seattle Parenting Examiner" but Kristy (2buzy) is filling that role for them.

She needs to examine her posts a bit more.

In Why Soy Milk Is Healthier Than Cows Milk she wrote:

Many people are lactose intolerant and will switch over to lactose-free cows milk. Trouble is it really isn't lactose-free. It actually contains an ingredient which breaks down the natural sugar leaving the milk (depending on the brand) only 70 to 99% lactose free. Soy milk on the other hand is 100% lactose free.

Soy milk is certainly 100% lactose free. But what about lactose free milk? Is it really only "70 to 99% lactose free"?

No. It really is 100% lactose free.

In the early days, we used to see lactose reduced milk, and this was indeed only 70 to 99% lactose free. Those days are long gone. I haven't seen lactose-reduced milk on the market for years.

Besides, the government has some rules companies must obey. One of them is that if a product advertises itself as lactose free, it must indeed be lactose free (within the limitations of the sensitivity of their measuring devices).

Major companies like Lactaid and Dairy Ease sell 100% lactose free milk. It really is lactose free. Kristy is wrong.

[Update. I posted this information as a comment on her page. The false information is no longer given, so apparently Kristy actually made the correction. She is the first person of all the ones that I've asked for corrections to acknowledge the error and make the change. That's admirable and much appreciated.]
