Normally stools are semisolid, with a mucus coating. Small pieces of harder, less moist feces can sometimes be seen impacted on the distal (leading) end. This is a normal occurrence when a prior bowel movement is incomplete; and feces are returned from the rectum to the intestine, where water is absorbed.

Fecal management
-
The management of feces is an issue of hygiene, since feces contribute to spreading of diseases and intestinal parasites. The problem of efficient management of feces has existed since the times when people started to live in permanent settlements, primarily for the reasons of cleanliness and odour.[citation needed] Toilets were known in ancient India (dated as early as 2,500 BC), in Ancient Rome, Egypt and China, although the contemporary flush toilet originated in 19th century Victorian England.[1] Night soil is a term most often used to describe the practice of using untreated human waste as fertilizer. ...

Until the end of the 19th century, the primary concern of sewage collection and disposal in the Western world was to remove waste away from inhabited places, and it was common to use waterflows and larger bodies of water as a destination of sewage, where waste could be naturally dissipated and neutralized. With the increased population density this is no longer a viable solution, and special processing of sewage is required. The lack of the latter is a grave sanitary and public health problem in developing countries. Urban areas require some methods for collection and disposal of sewage. ...
Tourism Nature reserve organizations, parks, and tourist agencies often issue regulations for tourists aimed at the prevention of the pollution of nature. In particular, catholes (cat holes), i.e., pits for feces, must be located at a reasonable distance (at least 60 m/200 feet) from water sources (rivers, lakes, etc.), to avoid possible bacterial contamination of water via precipitation, as well as away from trails. For faster feces decomposition, organic soil is preferred over sandy mineral soil. It is also recommended to avoid concentration of catholes around campsites. Filled catholes must be covered with a reasonably thick layer of soil, to prevent access by animals, some of which are coprophagous. It has been suggested that Reserve design be merged into this article or section. ...

Some areas require special instructions of human waste disposal. In rocky places, with the absence of soil, it is advised to spread feces thinly by smearing over rocks with good sun access for faster sterilization by UV radiation and drying.[citation needed] In larger snow fields, a larger distance (e.g., 200 m/650 feet) from trails and campsites may be mandated, if the waste is being disposed under snow. Note: Ultraviolet is also the name of a 1998 UK television miniseries about vampires. ...

It is recommended that the clinician correlate the symptoms and submit specimens according to laboratory guidelines to obtain results that are clinically significant. Formed stools often do not give satisfactory results and suggest little of actual pathologic conditions.
Three main types of microbiological tests are commonly done on feces:
- Antibody-antigen type tests, that look for a specific virus (e.g. rotavirus).
- Microscopic examination for intestinal parasites and their ova (eggs).
- Routine culture.
Routine culture involves streaking the sample onto agar plates containing special additives, such as MacConkey agar, that will inhibit the growth of Gram-positive, thick membranes organisms and will selectively allow enteric pathogens to grow, and incubating them for a period, and observing the bacterial colonies that have grown.

Color and odor variations of feces Yellowing of feces can be caused by an infection known as Giardiasis, which derives its name from Giardia, a tiny parasitic organism. If Giardia infects the intestines it can cause severe yellow diarrhea. This is a dangerous communicable infection and must be reported. Another cause of yellowing is a condition known as Gilbert's Syndrome. This condition is characterized by jaundice and hyperbilirubinemia. Hyperbilirubinemia occurs when too much bilirubin is present in the circulating blood. Giardiasis (also known as beaver fever) is a disease caused by the flagellate protozoan Giardia lamblia (also sometimes called Giardia intestinalis and Giardia duodenalis). ...

Gilberts syndrome, often shortened to the acronym GS, is the most common hereditary cause of increased bilirubin, and is found in up to 5% of the population (though some Gastroenterologists maintain that it is closer to 10%).

Feces can be black due to the presence of blood that has been in the intestines long enough to be broken down by digestive enzymes. This is known as melena, and is typically due to bleeding in the upper digestive tract, such as from a bleeding peptic ulcer. The same color change (albeit harmless) can be observed after consuming foods that contain substantial proportion of animal bloods, such as Black pudding or Tiết canh. The black color is caused by oxidation of the iron in the blood's hemoglobin. Black feces can also be caused by a number of medications, such as bismuth subsalicylate, and dietary iron supplements. Because liquorice is high in iron, this may also cause the feces to become black. Hematochezia is similarly the passage of feces that are bright red due to the presence of undigested blood, either from lower in the digestive tract, or from a more active source in the upper digestive tract. In medicine, melena or melaena refers to the black, tarry feces that are associated with gastrointestinal hemorrhage. ...

In children with certain illnesses, feces can be blue or green. Eating green or leafy food can turn feces green. Babies when digesting solid food for the first time also produce feces which tends to be green and of unusual consistency because of the presence of cells discarded during development of the digestive tract. Food with large amounts of food color can cause feces to be colored. An example is FDA Blue #5, which turns feces green when it reacts with bile in the intestine. The effect is considered harmless, and there have been no reports of ill effects. After a barium meal, the subsequent stool should be white. It is quite noticeable that a mostly vegetable diet will produce much less odorous feces than meat diets. The color of food is considered important in its enjoyment. ...

Fecal contamination A quick test for fecal contamination of water sources or soil is a check for the presence of E. coli bacteria performed with the help of MacConkey agar plates or Petri dishes. E. coli bacteria uniquely develop red colonies at temperature of approximately 43 °C (110 °F) overnight. While most strains of E. coli are harmless, their presence is indicative of more serious fecal contamination, and hence a high possibility of more dangerous organisms. See also Entamoeba coli. ...

Fecal contamination of water sources is highly prevalent worldwide, accounting for the majority of unsafe drinking water, which is the only water available to 1.1 billion people. In developing countries most sewage is discharged without treatment.
