CHA Hazard Identification & Risk Assessment 3

Question 1

A HACCP auditor reviews a hazard analysis that lists 'broken glass from overhead lights' as a physical hazard. Which preventive measure is most appropriate?

Accepted Answer

Installing shatter-resistant or shielded lighting fixtures

Answer

Shatter-resistant or shielded lighting prevents glass fragments from entering food if a bulb breaks, directly addressing the source of the hazard.

Question 2

Which of the following is a chemical hazard that can develop naturally in certain fish species if the fish is temperature-abused post-harvest?

Accepted Answer

Histamine (scombrotoxin)

Answer

Histamine (scombrotoxin) forms when bacteria decarboxylate histidine in scombroid fish (tuna, mahi-mahi) held at improper temperatures.

Question 3

In a hazard analysis decision tree, the question 'Does a control measure exist for the identified hazard?' leads to what outcome if the answer is 'No'?

Accepted Answer

Modify the process or product so that a control measure can be applied

Answer

If no control measure exists, the HACCP team must determine whether process or product modification is necessary to address the significant hazard.

Question 4

A mycotoxin such as aflatoxin is best categorized under which hazard type during HACCP hazard analysis?

Accepted Answer

Chemical — naturally occurring toxin

Answer

Mycotoxins like aflatoxin are chemical hazards because they are toxic compounds produced by molds, not the mold organisms themselves.

Question 5

When using a risk matrix to prioritize hazards, which combination warrants the highest priority for control?

Accepted Answer

High severity and high likelihood

Answer

Hazards that are both highly severe and highly likely to occur represent the greatest risk and must receive immediate control priority.
