A biological agent usually has no odor, color, or other signatures, while most chemical agents have one or more signatures.
A chemical incident is characterized by a rapid onset of medical symptoms, while the onset of symptoms from a biological incident could take days or weeks.
A biological incident can affect a larger geographic area, while a chemical incident can involve a smaller geographic area.

What were the four main of biological contamination?
Cultural, biological, physical, and chemical.
Is a garden salad a physical Or chemical change?
A biological process imply chemical and physical changes.
What are the biological and physical chemical appliction oxidiation and reduction?
The biological and physical chemical application of oxidation and reduction include contaminant reduction and mineralization of organic matter.
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
What are changes happen to the food?
Food undergoes physical, chemical, and biological changes during storage and preparation. Physical changes may include freezing, heating, or grinding. Chemical changes involve oxidation, browning, or fermentation. Biological changes occur when microbes grow and spoil the food.
What were the four main of biological contamination?
Cultural, biological, physical, and chemical.
What is the three main type of contamination?
Biological, Chemical, Physical These are the 3 hazard categories used in HACCP plans.
When storing raw fish in ice that is continuously draining helps prevent which type of contamination?
It prevents biological contamination.
What are different types of contamination?
There are four main types of contamination in water: Chemical, Radiological , physical, and Biological. The presence of contaminants is not necessarily a problem in itself. Many of the substances found in drinking water are harmless at low levels and some, like certain minerals, may even be beneficial.

What is foodborne illness and cross contamination?
Food contamination is when something makes the food inedible or can cause illness when consumed. Contamination can be # Biological (bacteria, parasites, viruses, etc.) # Chemical (cleaners, sanitizers, additives, etc.) # Physical (glass, metal, etc.) Contamination is not necessarily obvious or visible.

What are the 3 types of food contamination and give example to each?
Within USDA FSIS (Food Safety and Inspection Service), there are three categories of hazards that must be addressed within the regulated establishment's HACCP plan - chemical (cleaners, sanitizers, preservatives, etc.), biological (E. coli, Salmonella, Listeria monocytogenes, etc.), and mechanical (foreign particles, wood chips, metal flakes, etc.).
What are the problems posed by physical chemical and biological wastes?
Pollution.
What is the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
