how original, i prefer tostitos anyways, read and learn child: Until its modern spread, along with European culture, cheese was nearly unheard of in Asian cultures and in the pre-Columbian Americas. It had limited use in sub-Mediterranean Africa. Although it is rarely considered a part of local ethnic cuisines outside Europe, the Middle East, and the Americas, cheese has become popular worldwide through the spread of European Imperialism and Euro-American culture. The first factory for the industrial production of cheese opened in Switzerland in 1815. However, the large-scale production found real success in the United States. Credit goes to Jesse Williams, a dairy farmer from Rome, New York. Williams began making cheese in an assembly-line fashion using the milk from neighboring farms in 1851. Within decades, hundreds of dairy associations existed. Mass-produced rennet began in the 1860s. By the turn of the century, scientists were producing pure microbial cultures. Previously, bacteria in cheese was derived from the environment or from recycling an earlier batch's whey. Pure cultures meant a standardized cheese could be produced. The mass production of cheese made it readily available to the poorer classes. Therefore, simple cost-effective storage solutions for cheese gained popularity. Ceramic cheese dishes, or cheese bells, became one of the most common ways to prolong the life of cheese in the home. It remained popular in most households until the introduction of the home refrigerator in 1913.[32] Factory-made cheese overtook traditional cheese-making during the World War II era. Since then, factories have been the source of most cheese in America and Europe. Today, Americans buy more processed cheese than "real", factory-made cheese.[33]
