So if you go up to the butcher counter and get chicken wrapped up in butcher paper, that 2 day time period to use up or freeze would be much more accurate. I give myself 1-2 days past the date on the sealed chicken before I cook or freeze.
This bacterium is also known by the names hay bacillus, grass bacillus, or Bacillus globigii. Bacillus subtilis is an endospore forming bacteria, and the endospore that it forms allows it to withstand extreme temperatures as well as dry environments. Bacillus subtilis is considered and obligate aerobe, but can also function anaerobicly when in the presence of nitrates or glucose. Bacillus subtilis is not considered pathogenic or toxic and is not a disease causing agent. Bacillus subtilis has a flagellum which makes motility faster.
Bacillus cereus is a Gram-positive, rod-shaped, aerobic, motile, beta hemolytic bacterium commonly found in soil and food. Some strains are harmful to humans and cause foodborne illness, while other strains can be beneficial as probiotics for animals. It is the cause of fried rice syndrome, as the bacteria are classically contracted from fried rice dishes that have been sitting at room temperature for hours. B. cereus bacteria are facultative anaerobes, and like other members of the genus Bacillus, can produce protective endospores.
