Coffee Machines Stock Germs, Say Scientists

Scientists have found that all kinds of pathogens gather in coffee grounds and in used pod machine capsules.

According to the German News Agency (DPA), Fritz Titgemeyer, head of the Food Microbiology Laboratory at the Munster University of Applied Sciences in Germany, said that damp coffee grounds encourage the growth of germs.

If you leave a used coffee pod in the machine for a few days before throwing it out, some mould spores may remain in there and you may be adding them to your next brew.

Titgemeyer noted that a heat-stable poison may have developed, a so-called mycotoxin, and you will not be able to see or taste it.

The water containers and the plastic tubes in coffee machines are also a perfect breeding ground for bacteria if they are not cleaned properly. The expert said that bacteria can settle there in the form of biofilms. All removable components need to be cleaned thoroughly.

Titgemeyer added however disgusting it may be to imagine one's coffee machine full of microorganisms, they do not really pose a health risk.

"The water is heated to 80 degrees Celsius, which kills any germs present in the water tank," he said.

If you use the machine to make cold drinks, however, you may need to worry. Titgemeyer explained that in cold-extracted drinks like iced tea or iced coffee, all germs will remain. The good news is that many coffee machines include a self-cleaning program, but there are also extra things you can do to make sure you keep the germs at bay.

The strongest winds in more than a decade could hit Southern California on Tuesday, potentially causing structural damage and bringing extreme fire risk to areas that haven't seen substantial rain in months.

Beginning Tuesday afternoon, the windstorm will affect Los Angeles and Ventura counties and peak in the early hours of Wednesday, when gusts could reach 80 mph (129 kph), the National Weather Service said Monday.

Isolated gusts could top 100 mph (160 kph) in mountains and foothills, The Associated Press reported.

The weather service warned of downed trees and knocked over big rigs, trailers, and motorhomes. Powerful offshore gusts will also bring dangerous conditions off the coasts of Orange County and LA, including Catalina Island, and potential delays and turbulence could arise at local airports.
Public safety power shutoffs are being considered for nearly 300,000 customers across the region, according to Southern California Edison’s website.

The upcoming winds will act as an “atmospheric blow-dryer” for vegetation, bringing a long period of fire risk that could extend into the more populated lower hills and valleys, according to Daniel Swain, a climate scientist with the University of California, Los Angeles and the National Center for Atmospheric Research.

“We really haven't seen a season as dry as this one follow a season as wet as the previous one,” Swain said during a Monday livestream. “All of that extra abundant growth of grass and vegetation followed immediately by a wind event of this magnitude while it's still so incredibly dry," elevates the risk.
Recent dry winds, including the notorious Santa Anas, have contributed to warmer-than-average temperatures in Southern California, where there’s been very little rain so far this season.
Southern California hasn’t seen more than 0.1 inches (0.25 centimeters) of rain since early May. Much of the region has fallen into moderate drought conditions, according to the U.S. Drought Monitor. Meanwhile, up north, there have been multiple drenching storms.
Areas where gusts could create extreme fire conditions include the charred footprint of last month’s wind-driven Franklin Fire, which damaged or destroyed 48 structures, mostly homes, in and around Malibu.
The blaze was one of nearly 8,000 wildfires that added up to scorch more than 1,560 square miles (more than 4,040 square kilometers) in the Golden State last year.
The last wind event of this magnitude occurred in November 2011, according to the NWS, during which more than 400,000 customers throughout LA County lost power, the Los Angeles Times reported. At night, normally bustling streets were dim and left without traffic signals.
Planned power shutoffs for the public's safety, if deemed necessary, are projected to happen Tuesday and Wednesday, according to Southern California Edison.
“The grid is built to withstand strong winds,” said Jeff Monford, a spokesperson for the utility. “The issue here is the possibility of debris becoming airborne and hitting wires ... or a tree coming down.”
