Pakistan consumes a lot of milk, much of it delivered to the door unpasteurised, but increasingly in a packaged format. Few would question the quality of what is in the packages that are so widely advertised as paragons of purity and goodness, but they would be wise to do so. A recent study conducted by the Pakistan Council of Scientific and Industrial Research (PCSIR) on 16 brands of milk that are advertised as having been pasteurised and given Ultra High Temperature (UHT) treatment found that only six were fit for consumption. This information was shared with members of the National Assembly on Monday 31st January.
Untreated milk can be home to a range of unpleasantness, and if untreated has a short shelf life in its raw state. The dairy product manufacturers want to maximise the life of their products and thus heat milk to over 135 degrees Celsius to kill off harmful bacteria. Pasteurisation is a different process, heats the milk to a lower temperature and is designed to preserve those micro-organisms that are good for humans. Of the pasteurised brands tested only one was found fit for human consumption, whereas of the UHT brands tested only one was unfit, found to contain formalin and cane sugar. Contaminated foodstuffs are widely sold, and tests of 111 brands of bottled water in April 2016 discovered a range of toxins including sewage, sodium, potassium and arsenic. Out of the sample only 10 were fit for human consumption. As with water, so with milk. There is an increasing demand for ‘safe’ packaged food products and an increasing expectation that what is bought off-the-shelf in promoted packages lives up to the hype of the advertising agency. Reports such as that produced by PCSIR are a waste of effort if they are not acted upon. Sub-standard products must be withdrawn from sale immediately. The manufacturers must be prosecuted and the factories monitored by a health and safety inspectorate that does more than simply rubber-stamp. Worthless paper exercises serve no one well — clean up the milk industry.
