Update of FDA Drug Residue Testing in Milk

Published on: 07/03/2013
Author/s : Nicole Neeser, Minnesota Department of Agriculture (Dairy, Meat, Poultry, Egg and Compliance Program Manager)

Traditionally, drug residue testing on milk has been limited to the beta lactam testing requirements explicitly stated in the Pasteurized Milk Ordinance (2011 PMO, Appendix N, p. 342): "Industry shall screen all bulk milk pickup tankers, regardless of final use, for Beta lactam drug residues." Over the past twenty years, testing requirements have remained fairly limited in scope, despite the ava...

While responding to this topic, I am reflecting back and forward about the milk testing standards in Pakistan. Indeed the milk we are being provided either in UHT packing, polythene or through traditional milk men, literally it could be called anything but milk. In the beggining it was assumed that the extent of malpractising in milk preservation and mixing the traditional milk men rank highest, however, according to some unconfirmed reports the milk quality of large UHT milk companies is even worse and God knows what type of chemicals and hazardous chemicals are churned with milk to increase its quantity and thick. Due to traditional trend of milk shortages in summer months the intensity of malpractising of milk increase manifold. We it is a matter of concern for the concerned quarters and food standard agencies. Is there anyone listening.........????

In Pakistan Milk quality is questionable due to lack of proper testing. However, not only the authorities but the researcher's interest is required to go for routine quality testing.

Still we do not have standars of milk Quality in Pakistan. Malpracticing in milk sale is becoming a great concern and it is increasing day by day not only in fresh milk but in tetra packs, too. We are playing with the health of our community. Though some groups of farmers want to produce and sale quality milk with low health hazards however, it will definately cost more. In current circumstances consumers do not want to pay more. There is need to study and change the consumer behaviour and mind set first to get success.

All we have concerned about the milk quality. Once a leading company tried to export milk but whole UHT batch was rejected. It means whether milk is packed or open, standards are always poor. We should consider the main issues for this. The high input prices making dairy farming unprofitable, monoply of marketing and milk processing companies, high cost of advertisement, high cost of processing and overhead charges, poor production standards are the main culprits. A through value chain study is essential to put the industry on right track. The government monitoring policies are too weak and inefficient.

As a matter of fact milk quality issue has become complicated..all stake holders have left thinking about quality and standards and it has become mind set even for the consumers to live like that. to me following factors have contributed in this issue
1. huge gap between supply and demand
2. huge gap between supply n demand in summer
3. seasonal milk consuming pattern
4. lack of any monitoring and absence of writ of law in this field
5. purchasing power of the consumers
6. no incentive to farmers for producing high quality milk
7. High cost of production ( Increase in animal price, labour cost and input cost while price of milk did not reciprocate accordingly
Therefore a full fledged compign and plan is required to address this complicated issue in which both farmers, supply chain and govt should b included clearly thinking it as a National duty and in the interest of our future generation

As concern Milk standard than what about FMD occurring in this season
FMDV levels in milk
Most research on the occurrence of FMDV in milk, and nearly all research concerning
the effects of pasteurization or pH changes, has been done in cattle. FMDV can replicate
in the squamous epithelial tissues of the mammary gland, resulting in high viral titers in
milk.7;9 In some experimentally infected cattle, the highest viral titers found in milk were
comparable to levels detected in the pharynx.10 FMDV may be shed in milk before the
onset of clinical signs. During the 1967-1968 epizootic in England, this virus was
detected in some milk bulk tanks and tankers at least 33 hours before clinical signs were
reported in the affected herds. In some experimentally infected cows, it was found in
milk 1-4 days before vesicles developed.

There is relatively little published information on the amount of FMDV typically shed in
milk during outbreaks. The existence of seven FMDV serotypes (O, A, C, Asia-1, SAT-1,
SAT-2 and SAT-3) and a large number of strains may complicate this assessment, as the
amount of virus might vary between serotypes and strains. In a few field samples
collected from infected cows, the virus titer in milk varied from trace amounts to 106.6
TCID50/ml.10;11;35 One review article stated that peak virus shedding in cow’s milk is 106.7
TCID50 /ml milk, without giving further details.36 Alexandersen (2005) noted that, due to
the limited number of field samples, it is possible that some cows shed greater amounts of
FMDV than have been reported.

Commercial processing of dairy products includes clarification to remove debris, heating,
and various other procedures such as homogenization, evaporation, pH changes, drying
or filtration. Although the vast majority of research has been on the effects of heat, and
to a lesser extent pH, other processes could also affect the amount of residual FMDV in
contaminated milk products.

Only the Drugs residue is not the problems the animal suffering from different diseases for that drugs are used so first the disease affect the quality itself then drugs my upper comment look irrelevant but that acutely relevant with ultimate use of drugs and their affect.

A report on chemical adulterants in milk
February 10, 2014
Dear Nadem
To improve the milk quality you should be clear that what you mean by it. Hygienic or better composition. All depend on farm and feeding management. It is quite simple but needs professional approach. You can contact me in this regard.
