The only grass-fed beef store in my country puts the health benefits of grass-fed beef on their website (omega 3, fat soluble vitamins, ...). They also mention this :
Grain-fed cows have lower stomach acid. Because of this, E.Coli bacteries become more resistant. As grass-fed beef has less E.Coli, and their E.Coli bacteries are less resistant (and thus most likely to die in the human stomach), it is way more safe to consume.
Now when I looked up information about E.Coli, I found a guy with acne mentioning this :
Recently I made an micro-biological examination of the liquid content in the pimples and it turned out that they contain Escherichia coli (e.coli).
Would grass-fed beef be crucial in the paleo diet if your goal is to reduce acne?

If e coli is found in someone's pimples, it does not mean that it caused the pimples. E coli bacteria are often harmless.
If e coli caused one person's acne, it does not mean that it is a common cause of acne.
If one strain of e coli is found in cattle, it doesn't mean that the same strain causes acne. There are hundreds of known strains of e coli.
Grass-fed beef may be beneficial to your acne for other reasons than e coli. For example, lower omega-6 content and higher conjugated linoleic acid (CLA) in grass-fed beef could lead to lower inflammation in your skin.
Bottom Line: grass-fed beef may help your acne, but it is probably not because of e coli.
