According to this report on hot dogs by Clear Food, some hot dogs have human DNA in them.
2% of the overall samples had human DNA present.
What would cause human DNA to end up in the hot dogs? Does this have any food safety implications?

There is definitely no food safety concern here. While the report you cite makes a big deal out of this, implying that there's some kind of serious problem being detected here, in their FAQ they say:
It seems they're saying that this is all totally safe and allowed (by the people whose job it is to keep our food safe), and that the issue is one of transparency. I guess they think that food manufacturers should tell us that, as permitted by regulations, there are possibly tiny and completely safe amounts of human cells in food. But that seems pretty over-the-top; it's true about all food, so we'd have to slap that label on everything we eat.
Bottom line, food is not produced in a clean room environment. It's not a bunch of workers in bunny suits, being careful to not let a single skin cell float into the air and end up in your food; that'd be incredibly expensive and not provide any real benefit. So naturally, there's an opportunity for small amounts of human skin and hair to end up in your food.
And as Stephie pointed out, this is basically a DNA testing lab. Of course they have very sensitive equipment (which they also brag about in the FAQ), so they're able to detect things at a level that really shouldn't concern you. So as Lars also mentioned, it's kind of incredible that they were only able to find human DNA in 2% of samples. That means that 49/50 hot dogs are actually produced to a significantly higher standard than required!
Frankly, I think that report is presented fairly dishonestly. They deliberately neglected to mention in the initial results section that this is all safe, and instead implied that it was a problem you should worry about. Saying in the FAQ "What most people don't know..." hammers this home; they know that most people don't know this, and still didn't bother to say so.
