The pour plate technique is the typical technique used to prepare plate count agars. Here, the inoculum is added to the molten agar before pouring the plate. The molten agar is cooled to about 45 degrees Celsius and is poured using a sterile method into a petri dish containing a specific diluted sample.
The Food & Agriculture Organization believed the opposite of Mugabe's claims and suggested that Zimbabwe would most likely face an "overall food deficit of 1 million tons." [ 2 ] James Morris, the head of the World Food Programme (WFP), stated he was "personally overwhelmed," about the hunger crisis when visiting Zimbabwe in June, 2004.
The laboratory procedure involves making serial dilutions of the sample (1:10, 1:100, 1:1000, etc.) in sterile water and cultivating these on nutrient agar in a dish that is sealed and incubated. Typical media include plate count agar for a general count or MacConkey agar to count Gram-negative bacteria such as E. coli. Typically one set of ...
The Integrated Food Security Phase Classification (IPC), also known as IPC scale, is a tool for improving food security analysis and decision-making. It is a standardised scale that integrates food security, nutrition and livelihood information into a statement about the nature and severity of a crisis and implications for strategic response.
A somatic cell count (SCC) is a cell count of somatic cells in a fluid specimen, usually milk. In dairying, the SCC is an indicator of the quality of milk—specifically, its low likeliness to contain harmful bacteria, and thus its high food safety. White blood cells (leukocytes) constitute the majority of somatic cells in question.
The CFU/plate is read from a plate in the linear range, and then the CFU/g (or CFU/mL) of the original is deduced mathematically, factoring in the amount plated and its dilution factor. A solution of bacteria at an unknown concentration is often serially diluted in order to obtain at least one plate with a countable number of bacteria. In this ...
Spiral plating is used extensively for microbiological testing of food, milk and milk products and cosmetics. It is an approved method by the FDA. [2] The advantage of spiral plating is less plates used versus plating manually because different concentrations are present on each plate.
Zimbabwe's arable land surface is relatively small compared to major food producers in Africa, but its agriculture was rather well performing from 1961 to 2001 (up to 10% of African maize production in 1985). There are five natural regions that make up the agriculture of Zimbabwe. The first three regions are used for producing crops. [5]
