Researchers sampled 10 espresso brand espresso machines, zeroing in on the drip trays,

which catch those last drops of brown gold after a brew.

They found that nine of the ten machines harbored residues rich in enterococcus bacteria,

And another common resident was pseudomonas, which has both benign and pathogenic strains.

Pseudomonas appears to thrive in the presence of caffeine and even breaks it down,

which suggests the bugs might be put to work, decaffeinating coffee,

or cleaning caffeine residues from our waterways.

The findings appear in the journal Scientific Reports.

As for your next espresso shot, don't worry too much. The researchers did not find any
