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.

NEOM Nature Reserve Reintroduces Six Animal Species

As part of its bold rewilding strategy, NEOM has reintroduced more than 1,100 animals across six species to its expansive Nature Reserve—an important milestone in its broader mission to restore the region’s natural balance. With 95% of the region’s land preserved for nature, NEOM is working to rebuild self-sustaining ecosystems through habitat rehabilitation, species recovery, and cutting-edge ecological monitoring.

According to NEOM, when the Arabian Oryx was first reintroduced into the Nature Reserve in December 2022, it marked a milestone occasion, signifying the first time the animal had walked the sands of north-western Saudi Arabia for nearly 100 years, SPA reported.

In the early 1970s, the Oryx was extinct in the wild due to hunting and poaching, but conservation efforts across the region have seen its numbers swell in recent years, with more than 208 now calling NEOM home. Perfectly adapted to the region’s desert conditions, its white coat reflects the sun, while its complex nasal system cools the air it breathes and conserves water by recycling moisture as it exhales.

Another member of the Bovidae family, Arabian Sand Gazelles are petite, graceful animals that typically reside in sand dunes and coastal flats across the Arabian Peninsula. Gazelles are swift creatures, clocking speeds of up to 100 kilometers per hour in short bursts.

They are herbivores, and while NEOM’s regreening initiative continues to develop – with 4.7 million trees, shrubs, and grasses planted to date – the 530 Arabian Sand Gazelles currently residing in the reserve benefit from the natural vegetation that has returned to the area, following the removal of heavy livestock grazing. NEOM is also home to 223 Arabian Gazelles, which are typically darker in color and harder to find, preferring to reside in foothills and rugged mountain terrain.

Desert-dwelling wild goats can be found in NEOM’s rocky, mountainous terrain, and are typically recognized by their impressive arched horns. Males have backward-arched horns that can reach up to one meter in length, while females have much shorter horns and are lighter in color.

They are incredible climbers and have hooves with rubbery soles to act as suction cups on hard surfaces, aiding them in navigating steep cliffs to avoid predators, including wolves. NEOM has successfully reintroduced 53 Nubian Ibex to the reserve, adding to the population of several wild Ibex who have naturally returned to the area and are often caught on camera as part of NEOM’s monitoring program.

The red-necked ostrich, the largest and fastest living bird on earth, can stand up to 2.7 meters tall and weigh more than 150 kilograms. Their eggs are the largest of any living animal, measuring up to 15 centimeters long and up to 1.4 kilograms in weight. The bird gets its namesake from the fact that males have a reddish hue on their neck, especially in breeding season, when they perform an elaborate courtship display to attract females.

Currently, 27 chicks have been raised in NEOM Nature Reserve, which are well adapted to the region’s climate and feed on seeds, grass, leaves, and occasionally small insects or animals. Their strong legs allow them to run up to 70 kilometers per hour and, despite their size, red-necked ostriches are flightless.

Furthermore, the Lanner Falcon, last spotted in the wild in Saudi Arabia more than four decades ago, was reintroduced to NEOM Nature Reserve earlier this year in a momentous occasion. Known for its speed and agility, the Lanner Falcon can dive at speeds of more than 320 kilometers per hour. It has a striking appearance, with dark markings on its chest and belly, and a distinctive black moustache mark across its white face.

The release of Lanner Falcons into Bajdah at NEOM Nature Reserve forms part of a rewilding partnership between NEOM and the Saudi Falcon Club (SFC), which aims to reintroduce native falcon species within the Kingdom.
