metabolize carbohydrates in food, producing acidic by-products that damage enamel and dentin

Explanation:The bacteria Salmonella is typically found in foods that come from animals. These include meat, milk, cheese, and eggs. However, any food can become contaminated with Salmonella if it touches other contaminated food. Staphylococcus aureus is our final common type of bacteria that can cause foodborne illness.

metabolize carbohydrates in food, producing acidic by-products that damage enamel and dentin.

Explanation:

The bacteria that metabolizes carbohydrates in food and can lead to caries in the teeth are known as Streptococcus mutans. Streptococcus mutans are gram-positive organisms that produces acidic by products that damages enamel and dentin thereby leading to dental cavities.

Carrie has many cavities in her teeth because she doesn't brush her teeth effectively and often enough to remove the bacteria Streptococcus mutans. This bacteria in turn acts on the carbohydrates consumed by Carrie and convert it to acid leading to cavities and damage to Carrie's enamel and dentin.
