The single serve coffee machines certainly caught on quickly with consumers. And the sale of these appliances and the specially packaged single serving coffee has become a booming industry. There is a health risk to be aware of however.
KDKA-TV in Pittsburg recently performed an extensive swab test on almost 30 machines in Pittsburg, Chicago and Dallas. Lab results revealed the presence of over 4 million strains of bacterial colonies and mold in the holding tanks! The samples included strains as threatening as E.coli, staphylococcus, streptococcus and pseudomonas aeruginosa.
By their very nature, these machines are a constantly moist environment, ripe for microbial colonization. The good news is that there is no need to abandon your favorite brewer. A huge benefit can be gained from cleaning a machine that has been left standing for days by running a few cleansing brews through it before loading it with the coffee for your next batch.
There are some fairly simple steps you can take to prevent contamination to your machine:
–Routinely clean your machine.
–Run some vinegar through your machine.
–Consider using filtered instead of tap water.
–Don’t store water in between uses.
–Let it dry by leaving the lid off at night.
