Food Safety and Sanitation Chapter 2.1-2.2

When cooking and preparing food we want to make sure to do it safely.

Food Contamination

• Direct Contamination : this type of contamination is when food is exposed to the original source of the contaminant. Example: lettuce placed directly next to raw poultry.

• Cross-Contamination : this type of contamination is indirect where food is exposed to harmful elements through improper use of tools, equipment, products, or procedures. Example: Cutting board contaminated with raw food and then used to cut produce ; unsanitary hands handling food.

Steps to take to prevent contamination

Multiple Choice

If I am making salad and grilled steak strips which should I prepare first and why?

• Prepare the steak strips first and then keep on warm while you make salad so it is all done at once.

• Prepare salad first so all raw food items are cut and in container before dealing with raw meat to prevent cross contamination.

• Prepare salad first so when you steak is done everything will be ready at once.

• The order doesn't matter.

Food borne illness is most often caused by pathogens.

• Pathogens are microorganisms that cause disease.

• Pathogens that cause food borne illness are categorized as either: biological, physical, or chemical contaminants.

Biological contaminants

A biological contaminant is a living microorganism that can be hazardous if inhaled, swallowed, or otherwise absorbed into the body system.

EXAMPLES:

Food spoilage indicator includes change in food color, odor, and/or texture. 1. MOLD is an example and it multiplies fastest on acidic foods with low water content. 2. Parasites is another example which rely on host for survival and livein stomachs and intestinal tracts of animals which pass on to humans when meat is consumed. 3. Viruses are another pathogen that survives inside cells of hosts - humans host viruses and pass it on through sneezing or coughing - can survive on food surfaces or production equipment. 4. Bacteria is another example that survives in soil, water, or organic matter which includes bodies of plants and animals.

Mold

Can we eat the "clean" part of the moldy bread?

Parasites in food

This is not for the weak of stomach, but knowledge you should know.

Here's an article that describes parasites and bacteria you may find in food.
