Food sanitation

   In rural areas, animals are slaughtered on a slaughter slab. In an urban area, this is carried out in a slaughter house. An abattoir, that are found only in most developed countries, is a modern slaughter house with equipment for the proper, hygienic and humane slaughtering of animals.
Public health inspectors have to be present before the slaughtering of animals to examine them. The inspectors have to certify by observation that the animals are free from diseases like anthrax, rinderpest, foot and mouth disease. Very young animals and diseased animals cannot be killed for meat production.
The inspector then ensure that the healthy animals are slaughtered in humane manner. The inspector will carry out a postmortem examination on the slaughtered animal to ensure that it is free from the following diseases and parasites. Mostly pigs and cattle suffer from more diseases than goats and sheep.
    Public health inspectors send samples of vegetables, fruits, cooked, preserved and canned foods to the laboratory for analysis. This is to ensure that these foods do not contain harmful chemicals. Canned foods are analysed to make sure that their contents agree with what is given on their labels. Inspectors also check and condemn all dented and bloated tins of foods, eating food from such tins is usually harmful.
  Public health inspectors should regularly check eating shops and restaurants and the kitchen of hotels and inns. If these places do not meet the required sanitary standards, their license should be withdrawn. Public health inspectors have to ensure that food handlers should undergo medical check ups, so that carriers of infectious diseases can be detected and treated. They should also have to ensure that food handlers are healthy and maintain a high standard of personal cleanliness..

Natural soil

 Natural soils are influenced by rainfall and temperature,heavy rain causes the soil to become leached. High temperatures increase the rate of decomposition of organic matter in the soil, thereby lowering its humus content. Thus, climatic conditions tend to produce poor soils in the tropics and rich soils in the temperate regions. Besides climate and vegetation, the parent rock material also contributes to the quality of the soil. For example volcanic rocks tend to produce fertile soils.    Laterite, a red soil which is a product of leaching, is commonly found in the tropics. It is composed mainly of iron and aluminium compounds,and poor in humus and essential plant nutrients, such as phosphorus, nitrogen and potassium. The black and brown soil of the temperate grasslands are the world's richest soils, with a high mineral and humus content. The light coloured desert soils tend to be very rich in minerals but have a low humus content.    Mainly the soils ar...

Rock Formation

A rock may be defined as a hard compact mass made up of cluster of primary or secondary minerals. The primary minerals are those that are as they were made in nature. Some of them are Quartz, Olivine, Pyroxene, Hornblende, Biotite, Muscovite and feldspar. On the other hand, secondary minerals consists of particles worn out from original minerals which have combined with other elements. They exist in form of: (i) Oxide such as those of magnesium, Iron and Aluminum. (ii) Sulphates and carbonates of Iron, Magnesium and Calcium. (iii) Clay minerals such as the silicate clays and the hydrous Oxide.   TYPES OF ROCKS (i) Igneous rock (ii) sedimentary rock (iii) Metamorphic rock. Based on their chemical composition, we have basic and acidic rocks. Granite is a very good example of an acid rock. PROCESSES OF ROCK FORMATION IGNEOUS ROCK :This is formed through the process of cooling and hardening of the molten magma. This molten magna is confined deep down below the earth crust und...

Tin ore

    Tin ore and columbite are two minerals that co-occur in the form of heavy black grains like gunpowder, mixed with sand and gravel. They are deposited in alluvial beds of old river valleys and subsequently buried under layers of soil overburden. The ore is mined by the open cast method. To do this, a powerful machine called a dragline is used to first remove the overburden, and then to scoop out the tin ore which it piles in heaps called a monitor is used to direct a powerful jet of water to this tin wash, which washes it down through a series of sluice boxes. Here, the black, heavy tin grains together with other minerals like columbite, now called tin concentrates, sink to the bottom of the boxes, while the water carries the dirt and sand away.     At this stage, the columbite grains are separated from the pure tin concentrates. The concentrates are then sent to factories to be smelted refined and moulded in bars called tin ingots. It is in the form of either ...
