Question Title

* 1. Enter your first and last name

Question Title

* 2. Strategic sampling is one of the procedures recommended by the NMC. What is it designed to do?

It is used to help choose a cleaning system that uses water as efficiently as possible.

It is used to help identify sources of microbial contamination and resolve high bacteria count problems in milk.

It is designed to diagnose diseases the cow might have.

It is used to help of create a good combination of milking procedures to manage the parlor efficiently.

Question Title

* 3. Strategic sampling is a procedure that comes into play after bulk tank analysis indicates that equipment sanitation or incubation is a major source of bacteria in the farm's milk.

True

False

Question Title

* 4. Strategic sampling can help identify the exact source of the bacteria problem which will lead to finding the most effective method to solve it.

True

False

Question Title

* 5. Select the best two answers. Strategic sampling of milk should be done atdifferent and in the milking process.

Intervals

Locations

Situations

Times

Temperatures

Question Title

* 6. Select all that apply. The following are locations that should be sampled in order to help determine if the source of the bacteria is a cleaning failure and/or incubation problem:

In the milk-line and receiver

In the milk transfer line (after filters and pre-coolers)

Inside the bulk tank

Question Title

* 7. Why is it important to do strategic sampling of the milk at different times during the milking process?

It helps determine if there is significant bacterial incubation within the system during the cleaning process.

It helps determine if there is significant bacterial incubation within the milk handling system during the milking process.

It is not important to do strategic sampling at different times in the milking process.

It helps determine if the pasteurization process is working adequately.

Question Title

* 8. Select all that apply. The following are times in the milking process that should be sampled in order to help determine if bacterial incubation is significant within the milk handling system.

After the first group of cows is milked

After every 4 hours of milking (or since the system has been washed)

At the end of milking (or before the next wash cycle)

Question Title

* 9. What do elevated counts in the receiver at the beginning of milking likely indicate?

Cleaning failure in transfer line and equipment between receiver and bulk tank (e.g. plate coolers or milk filters)

Cleaning problems in the milking units, milk meters, milk line or hoses

Incubation within the milk handling system

Question Title

* 10. What do elevated counts in transfer lines but not in the receiver after the first group of cows indicate?

Cleaning failure in transfer line and equipment between receiver and bulk tank (e.g. plate coolers or milk filters)

Cleaning problems in the milking units, milk meters, milk line or hoses

Incubation within the milk handling system

Question Title

* 11. What does a continual rise in counts during the milking process indicate?

Cleaning failure in transfer line and equipment between receiver and bulk tank (e.g. plate coolers or milk filters)

Cleaning problems in the milking units, milk meters, milk line or hoses

Incubation within the milk handling system
