The document discusses quality measures across the Indian dairy supply chain. It notes that India has over 350 million smallholder dairy farmers and is the world's largest milk producer. However, quality issues exist such as high bacterial loads and antibiotic residues in raw milk. The document outlines various contamination risks and control measures at the farm, collection, processing, storage, and transport stages. These include animal health protocols, clean milking practices, quality testing of raw milk, use of quality management systems like HACCP, and support services to promote clean milk production. The overall aim is to provide safe, high-quality dairy products to consumers while addressing challenges across the complex dairy production chain in India.

4. Quality Concerns in Dairy Processing
Processors must contend with the following problems on a
daily basis :
High bacterial loads in raw m ilk are reducing product
shelf life;
High bacterial counts in raw m ilk are a direct cause of
reduced quality in dairy products
Antibiotic residues prevent efficient yogurt and cheese
production
Antibiotic and pesticide residues do not m eet regional
trade standards and thereby restrict ex port trade
A lack of cold chain in collection system s reduces quality
A lack of cold chain at retail reduces distribution
efficiency and causes products to spoil quick ly
Consum ers have inaccurate perceptions about poor m ilk
quality, even w ith processed products.

5. Clean Milk Production at Farm level
Clean milk production results in milk that :
I s safe for hum an consum ption and free
from disease producing m icroorganism s;
Has a high k eeping quality;
Has a high com m ercial value;
Can be transported over long distances;
I s a high quality base product for processing,
resulting in high quality products.
6. Contamination and Control Measures at
Farm Level
Contamination of milk can occur at the following
levels:
Anim al shed and environm ent
The Anim al , its health and m anagem ent
M ilk er and m ilk ing routine
M ilk ing equipm ent
Storage and transport
7. Quality Measures In Milk Collection Systems
Animal Shed
The anim al shed is one of the m ain sources of
contam ination.
M ud, urine and feed residues should regularly be
rem oved from the shed.
The shed should have proper drainage, sufficient light
and ventilation.

The m ilk ing area of the shed needs special hygienic
attention.
The floor of the m ilk shed should be sw ept w ith clean
w ater, and disinfected w ith one-percent bleaching
pow der solution.
8. Animal Health Care
Milk from diseased animals should be kept separate and
disposed of safely.
Animals suffering from any contagious disease, including
mastitis, should be segregated from the healthy ones.
The skin of the animal provides a large surface for possible
contamination.
Long hairs on the flanks, hind legs, tail and udder should be
clipped at frequent intervals.
If washing of animals is not practiced regularly as is
observed in most cases, at least grooming of the animals
should be done to keep the hair and dust away from milk.
The udder is the part of the animal nearest to the milk and
needs to be washed before each milking, and dried with a
clean cloth or towel.

14. Storage and Transport
Before storage, it is best to filter the milk with a clean cloth in
order to remove large particles that might have entered the milk.
The cloth should be thoroughly cleaned after use and left to dry in
the sun.
Heat, light and violent movement can all cause breakdown of
certain components in the milk. Milk should therefore be cooled as
quickly as possible.
In case chilling is not feasible, preservatives like lactoperoxidase
can be added to prolong the time before the milk gets spoiled.
Milk should be stored in clean containers with a lid and kept in a
cool and shady place where the danger of contamination is
minimal.
Milk should be transported in clean containers, transport time
should be kept to an absolute minimum and violent movement of
the milk should be avoided as milk fat can soon turn rancid in the
presence of oxygen.
15. Food Safety
Society requires food safety which calls for integrated product
traceability from farmer to consumer
As a consequence, data driven challenges arise:
Sufficient granularity in traceability data requires batches as sm all as
possible in order to recall them in case of quality problem s.
Ever-growing consumer choice resulting from food manufacturers
expanding their product offering leads to strong SKU proliferation
This sets new standards for system capabilities.
In the area of outlets, retailers’ shop layouts are determining the
method to deliver the goods, asking, for example, for sequencing
during loading
This adds to the com plex ity of m aterial handling.
To comply with global standards, retailers are auditing their food
producers frequently on many aspects
These include respecting HACCP and general hygienic rules, am ong
other things.
Obviously, this doesn’t m ake the processes landscape any sim pler.
16. Support Services
Milk Producers Organisations (MPOs) should provide “Support-
Services” to increase clean milk production.
An effective and well trained animal health service should be
available at all times to look after the health of animals,
arrangements should be made for regular vaccination and
checking against contagious diseases by the qualified
veterinarians.
Veterinary first aid should be readily available around the clock
at village level.
To avoid spoilage, milk collection centres should be set up at
locations that are easily accessible to the producers.
Since such programmes benefit all and sundry - may it be
manufacturer, employee, supplier, custom packer, distributor,
retailer, consumer, regulatory authorities and the nation as a
whole, they deserve a national generic promotion campaign to
create an awareness amongst the public at large.
17. Conclusion
Raw milk quality control at the village level is a very
challenging task and has to be taken up considering the
long term perspective for making Indian Dairy products
acceptable in the international arena.
Providing a safe, high-quality and nutritious dairy
product to the consumer is need of the hour although
challenging because all aspects of the production chain,
from the farm to the consumer, must be considered.
