* 2. One source of bacteria in raw milk is the environment, from which microorganisms are drawn into the milking system.

True

False

Question Title

* 3. The first rinse is performed immediately after all of the cows are milked, it will remove most of the residual milk in the system, and its temperature should be between 38°C and 55°C (100°F and 130°F).

True

False

Question Title

* 4. Select all that apply. What are important points to evaluate in order to assess the CIP procedures of a milking system?

the chemical concentrations at the beginning of each cycle

the temperature of the water returning to the wash sink at the beginning and end of each cycle

the frequency that each cycle is performed

the color of the chemicals at the beginning and end of each cycle

the frequency of milk filter replacement

Question Title

* 5. The three most important tests of bulk tank milk to aid in cleaning diagnosis are:

somatic cell count (SCC)

standard plate count (SPC)

thermoduric (or LPC) count

protein content analysis (PCA)

biochemical characteristics analysis (BCA)

coliform count

Question Title

* 6. High raw milk bacteria counts might be due to:

poor pre-milking cow teat hygiene

contamination with mastitis organisms

problems with equipment cleaning and sanitation

incubation of bacteria within the milk handling system during the milking process

all of the above

Question Title

* 7. What is the most likely result of a milking system cleaning failure?

mastitis organisms become the main source of milk contamination

bacteria in the milking machine multiply and appear in bulk tank milk

the cow housing environment becomes contaminated

all of the above

none of the above

Question Title

* 8. Why should bacterial evaluations of bulk tank milk be performed periodically on farms?

to assure compliance with national, state, and local milk processing requirements

to determine the types of mastitis bacteria that may be present in the herd

to improve the ability to diagnose sources of bacterial contamination

to help dairy processors monitor and improve milk quality

all of the above

Question Title

* 9. Routine bulk tank evaluations can be used to assess:

the types and levels of mastitis pathogens in a herd

the cleanliness of cows in their housing environment

the quality of pre-milking sanitation

the effectiveness of milking equipment cleaning and sanitation

all of the above

Question Title

* 10. Select the best answer. A failure in the cleaning of milk handling equipment can result from a failure in the , , or _ processes.
