No, butter is not a bacteria. Butter is a dairy product made by churning cream to separate the butterfat from the buttermilk. While bacteria can be involved in the fermentation process of some types of butter, such as cultured butter, butter itself is not a living organism but rather a food product.
Refrigerated butter is mostly safe. The pasteurizing process prevents bacteria in the butter, and then the high fat content is not ideal for bacterial growth. Bacteria on butter would be mostly caused by contamination with other items. For example; E. Coli on butter would be caused by cutting butter with the same knife used to cut meat containing E. Coli.
The peanut butter is acting as a carrier rather than a growth medium. The peanut butter was contaminated, the bacteria survived, and the consumers got sick.
Salmonella...
No. It may kill any bacteria, but the butter will still smell and taste rancid.
Most butter doesn't use bacteria in it's formation. It's just pure milk fat. There could be some butters that are special processes that use bacteria in some way but put butter is extracted from cream by agitating the cream until the milk fat separates from the cream and forms lumps of butter.
Cultured butter is butter which has had live bacteria added to it before churning which gives it a tart flavor. Culturing butter is more common in Europe than in the United States.
