Abstract/ Executive Summary:

The bacterial load was not uniform in different points of production in the same farm and within farms. From the results it is observed that in all three points TVC were the lowest (54.5x104 /ml) in ZDF followed by a higher count (58.8x104 /ml) of FMP (Vitamilk) and the highest (77.6x104 /ml) in BKK (Pusti). The TVC increased progressively from the first point to the third point as recorded in sample of all farms but this increase was found to be the lowest in milk samples of ZDF. It may be due to hygienic care and handling of milk, proper cleanliness of utensils and minimum period required during production at different points and rapid cooling of milk. The TVC/ml of milk samples of FMP (Vitamilk) as well as BKK (Pusti) from point-1 towards point-2 increased poorly but from point-2 to point-3 the rate of increase was rapid. It may be attributed to longer time interval of packaging of milk and unhygienic practices.

Program Area: Quality and Nutrition

Commodity: Milk

Objectives:

It is therefore important to ensure high quality raw milk from healthy animals under good hygienic conditions and that control measures are applied to protect human health.

Methodology:

For the study Zihan dairy farm (ZDF), Sherpur, Fatema Multi Project (FMP) (Vita Milk), Mymensigh and Beltali Krishi Khamar (BKK) (Pusti), Mymensingh were selected. Raw milk samples (100ml) were collected aseptically into sterile bottles from three different points of each farm- one (point-1) from milking bucket of each milk collection unit/point (MCU) immediately after milking from individual cow, another (point-2) from bulk cans of each MCU after mixing of milk of different cows and last (point-3) from polythene packaged milk sold to retail stores. Bottles were kept in a large wide mouthed thermo flasks kept cool in ice and then processed immediately for delivery to the Laboratory of Microbiology, Department of Microbiology and Hygiene, Bangladesh Agricultural University (BAU), Mymensingh. A total of 30 samples (10 samples from each unit) of each farm were bacteriologicaly examined and microorganism counts were expressed in colony forming units (cfu) per ml of milk. The foregoing prepared diluted samples were subjected to Total Viable Count (TVC) in the Laboratory as well as to detect and enumerate coliform and staphylococci. TVC was accomplished according to the method described by Quinn et al. (1994) who prescribed serial tenfold dilution of the milk samples. The technique followed to determine the TVC by pour plate method on nutrient agar, MacConkey agar and Manitol salt agar.

Achievement/Findings:

The milk samples of first point of all the farms were of the best quality because TVC, coliform count and staphylococcal count/ml were the lowest at this point of production at all the farms.
