Common Foodborne Pathogens: Salmonella

Salmonella species are common, naturally occurring bacteria found in the intestinal tracts of many animals and birds. When certain species of Salmonella are transferred from animals to humans – often through food contaminated with animal feces – humans experience symptoms of Salmonella poisoning.

Salmonella species are a leading cause of foodborne bacterial illnesses in humans. Human salmonellosis (the disease caused by Salmonella) is generally increasing worldwide. Poultry, beef and eggs are the predominant reservoirs of Salmonella species with other foods (fruits and vegetables) as potential vehicles for infection.

Dry Curing Virginia-Style Ham

Virginia ham was one of the first agricultural products exported from North America.

Foodborne Pathogens: E. coli O157:H7

What is E. coli O157:H7?

Escherichia coli is a common bacterium found in the human intestinal tract and vital to the proper functioning of our digestive system. While most strains of E. coli are beneficial to humans, a few are pathogenic. The most infamous example is E. coli O157:H7.

While this bacterium is too small to be seen without the aid of a microscope, E. coli O157:H7 is capable of causing serious damage to our digestive tract. First discovered as a foodborne pathogen in 1982, numerous E. coli O157:H7 foodborne outbreaks have been documented.

Información Esencial Sobre la Seguridad de los Alimentos: Una Guía Para Padres y Proveedores de Cuidado de Niños

Los microbios o bacterias pueden ser benefíciales pero también perjudiciales. Los alimentos pueden tener microbios buenos y malos. Las bacterias “buenas” tales como las bacterias en el yogurt nos ayudan a digerir alimentos y la levadura que nos ayuda a preparar alimentos como el pan. Los microbios o bacteria “malas” pueden causarnos enfermedades. Para los niños pequeños, las bacterias malas pueden ser especialmente dañinas porque ellos todavía están formando su sistema de defensas o sistema inmunológico.

Pressure Canning

The process for canning foods in the home depends on the acidity of the food, which is determined by its pH. Low-acid foods have a pH more than 4.6, and high-acid foods have a pH less than 4.6. In general, vegetables and meats are low-acid foods, and fruits are high-acid foods. High-acid foods can be safely processed in a boiling water bath, but low-acid foods must be processed in a pressure canner.
