| Green Plants and Fruits
The natural surface flora of plants varies with the plant but usually includes species of Psuedomonas, Alcaligenes, Flavobacterium,
Micrococcus and coliforms and lactic acids bacteria. Bacillus
species, yeast and molds also may be present.The number of bacteria will depends
upon the plants and its environment. |
AnimalsHides, hoofs, and animal's hair
contain not only larges number of m/o from soil, manure, feed, and water but also important
kinds of spoilage m/o. The skin of many meet animal may contain micrococci, stapilococci, and beta streprococci.

| Sewage When untreated domestic sewage
is used to fertilized plant crops, there is a likelihood that row plant food will be
contaminated with humas pathogens. In addition to the pathogens, coliform bacteria, anaerobs,
enterococci and etc. can contaminate foods from this source. Natural waters contaminated with sewage
contributes their m/o to shellfish, fish and other seafoods. |
SoilThe soil contain the greatest variety of m/o
of any source of contaminations. Soil contains various of molds, and yeast as well as higher bacteria
such as actinomycetes and iron bacteria. |
| WaterNaturals water contains not only their
natural flora but also m/o from soil and posibbly from animals or sewage.The kind of bacteria
in naturals water are chiefly species of Psuedomonas, Chromobacterium, Protues, Micrococcus
and Basillus. |
AirTotals number of m/o in a food maybe increased
from the air, especially if the air is being used for aerationof the products.Molds spores, because
of their small size, resistance to drying are usually present in air. Yeast, are found in most samples
of air. |
