Chapter 25, Problem 1CF

Summary Introduction

To explain:

The reason why pasteurized milk is used in the US.

Concept introduction:

Pasteurization is the process of treatment of food and beverages to keep them safe for a long period of time. The process involves the heat treatment of the substance at a specific temperature for a particular time period. Then the products obtained are cooled and packaged at suitable temp and with preservatives. Pasteurization process helps in increasing shelf life of the product.

Explanation of Solution

Selling raw milk in the US comes is a crime. The pasteurization was declared as standard procedure in the US by the year of 1950s.

Pasteurization is used in the US because this process kills bacterial species which can spread infections and diseases. Some cases of spread of disease occurred in the US because of consumption of raw milk of animal origin (cow/buffalo).

The raw milk may store some harmful microbes such as E. coli and Salmonella. So, in the US pasteurization is a standard practice to kill all the microbes present in the milk hence securing the population from the infections and diseases.

Conclusion

In the US pasteurization of milk is used to prevent the population from the infections and diseases that is caused by consumption of raw food product. Pasteurization heat kills the microbes present in the raw milk.

Summary Introduction

To explain:

Why the unpasteurized or raw milk is a concern of health.

Concept introduction:

Pasteurization is done to heat kill the bacteria and other infection causing agents. The heat killing procedures save the population from the attack of various kinds of infectious agents which had contaminated the raw milk.

Explanation of Solution

Pasteurization of the milk is a process to kill the microbes present in the raw milk.

Raw milk or unpasteurized milk is a concern of health because there are high chances that the raw milk is contaminated with the several infection causing agents. The raw milk may store several bacteria such as Listeria, Salmonella, Escherichia coli, Campylobacter.

These bacteria or infection causing agents can cause infections and disease (as if one consume this affected milk/food product), so if the milk is pasteurized than it can prevent the spread of infectious agents.

Conclusion

Raw or unpasteurized milk is a matter of health concern because raw milk can contain several infections causing agent which can cause infection after consumption.
