Enterococcus faecium? Probiotics

I have recently bought a probiotic that contains the following:-

Lactobacillus acidophilus, Lactobacillus salivarius, Lactococcus lactis, Enterococcus faecium, Lactobacillus casei, Bifidobacterium lactis, Bifidobacterium longum, Bifidobacterium infantis

Is Enterococcus faecium safe to take? I have been doing some research on it and some people say it is safe, others disagree. If anyone with any knowledge of this could help me, it would be much appreicated. Is it safe to take if you have 'leaky gut'
syndrome.

Thanks
