Bacteria, parasites, viruses, yeast, fungi and molds capable of causing disease that can only be viewed with a microscope. Food items infected with a pathogenic microorganism usually look no different than an uninfected food item.
include algae, bacteria, mold and fungus. Control of microorganisms is the reason pool and spa water require continuous sanitizing with chemicals or methods such as chlorine, bromine, biguanide, algaecides, ozone, ionization, ultra-violet, etc.
Independent organisms of microscopic size, including bacteria, yeast, and mold. When alive in a suitable environment, they grow rapidly and may divide or reproduce every 10 to 30 minutes. Therefore, they reach high populations very quickly. Undesirable microorganisms cause disease and food spoilage. Microorganisms are sometimes intentionally added to ferment foods, make antibiotics, and for other reasons.
Very small living organisms that can only be seen through a microscope. Some microorganisms use the wastes in wastewater for food and because of this are used as part of the wastewater treatment process.
Bacteria, yeasts, simple fungi, algae, protozoans, and a number of other organisms that are microscopic in size. Most are beneficial but some produce disease. Others are involved in composting and sewage treatment. Milligrams/liter (mg/l): A measure of concentration used in the measurement of fluids. Mg/l is the most common way to present a concentration in water and is roughly equivalent to parts per million.
means yeasts, molds, bacteria, viruses, and other similar microscopic organisms having public health or sanitary concern. This definition includes, but is not limited to, species that: (1) Have public health significance; (2) Could cause a component, dietary ingredient, or dietary supplement to decompose; (3) Indicate that the component, dietary ingredient, or dietary supplement is contaminated with filth; or (4) Otherwise may cause the component, dietary ingredient, or dietary supplement to be adulterated. Must is used to state mandatory requirements. [Definition from Proposed Rule: Current Good Manufacturing Practice in Manufacturing, Packing, or Holding Dietary Ingredients and Dietary Supplements; 68 FR 12251
Simple unicellular and structurally similar representatives of the plant and animal kingdoms. With few exceptions, the unicellular organisms are invisible to the naked eye and generally have dimensions of between a fraction of a micron and 200 micron.
