HACCP Flashcards

1
Q

What form may the cost of foodborne illness take?

A
  • Medical expenses
  • Loss of sales
  • Legal fees and fines

Foodborne illness has a major economic impact. It costs society billions of dollars each year (US figures). These cost occur in the form of medical expenses, lost work, and reduced productivity by victims of the illness, legal fees, punitive damages, increased insurance premiums, lost business, and loss of reputation. Consumer confidence also goes down when a foodborne disease outbreak is reported. Food establishments that have been linked to a foodborne illness are likely to receive more frequent inspections by regulatory agencies. The establishment can also be closed if it is determined that is the best way to protect public health. A foodborne disease outbreak will have a negative impact on the owners, managers, and employees of the food establishment where it occurred and on the rest of the food industry as well.

Q

Which demographic is not especially susceptible to foodborne illness?

A

Young adults

Foodborne illness can cause severe reactions, even death, to those individuals in high risk categories. The availability of a safe food supply is criticial to these people. This is an important consideration when completing Form 1. The intended use of the product should be based upon its normal use by end users or consumers. The HACCP team must specify where the product will be sold, as well as the target group, especially if it happens to be a sensitive portion of the population (i.e. senior citizen homes, hospitals, baby food).

42
Q

What are biological hazards?

A

Biological hazards are those caused by micro-organisms (bacteria, virus, parasites and moulds) and are often associated with the failure of a process step. (e.g., Pathogen survival due to improper time/temperature applications during pasteurization)

43
Q

What are chemical hazards?

A

Chemical hazards include those caused by substances/molecules that:

  • Are naturally derived from plants or animals (e.g., poisonous mushrooms);
  • Are intentionally added to the food during growth or during food processing. These substances are considered safe at established levels but are dangerous above these levels (e.g., sodium nitrite, pesticides);
  • Contaminate the food accidentally (e.g., cleaning chemicals);
  • Cause some individuals to experience an immune system response (food allergens).
44
Q

What are physical hazards?

A

Physical hazards include substances not normally found in food that can cause physical injury to the person consuming the food (e.g., wood slivers, glass fragments, metal shavings, bone pieces).

45
Q

Describe conditions where L. monocytogenes can survive.

A
  • High salt concentrations
  • High acid levels
  • Low temperatures to 0.1 degree C

They also form biofilms that are difficult to remove.

  • Acidity (pH)
  • Temperature
  • Time
  • Oxygen/no oxygen
  • Moisture (water activity)
47
Q

Which temperatures do bacteria grow at?

A
  • Temperatures below 4ºC slow or inhibit most bacterial growth

  • Freezing prevents growth of bacteria but some bacteria can survive freezing
48
Q

What is the danger zone?
