Almost eternal: some bacterial spores are able to survive for several hundred years.

Bacillus cereus
(spore-forming bacterium)

Bacillus cereus is an aerobic, Gram-positive, rod-shaped bacterium of the Bacillaceae family being able to form spores. Bacillus cereus is one of the possible causes of meningitis or catheter-associated urinary tract infection. In most cases, it is resistant to penicillin.

Bacillus cereus is transmitted to food like rice via dust and soil particles and thus causes food poisoning.
