Consumers want to be confident that their dairy products are safe, natural, healthy, and free of contamination.
Antibiotic residues in milk are a serious problem for human health. There is a concern that small amounts of certain antimicrobial agents may significantly shift the resistance patterns in the microbial population in the human intestinal tract. The residues could cause allergy and hypersensitivity in humans.
Antibiotic residues could also interfere with dairy ingredients and decrease their performance, resulting in scrapping and major losses for the dairy plants. They could delay the starter cultures’ activity and impact the curd formation of milk, causing improper ripening of cheeses.
Why antibiotics?
That is why all parties along the milk chain are interested in the absence of the residues in the milk– milk producers, milk purchasers and processors, the enforcement authorities, and consumers.
Drugs are administered to dairy cows for the treatment of mastitis and for disease therapy. Many drugs are retained in the animal body for longer times than indicated by label discard times. Consequently, milk samples remain positive for residues.
The primary control is on the farm and begins with the correct prescription and administration of the antibiotics and the careful adherence to withdrawal periods. In short, milk producers must ensure that milk from animals under treatment or in the withdrawal period does not enter the food chain. The primary controls are complemented by the testing of milk for antibiotics, undertaken by food businesses at various points in the supply chain, including on farm. It is up to individual food business operators (including milk producers) to determine their own sampling and testing regime.
In order to ensure food safety, the EU authorities imposed strict concentration limits for antibiotic residues. Chr. Hansen, now Novonesis, offers a complete range of antibiotic test kits to prevent the negative effects of antibiotic residues and to ensure that the milk processed at dairies is free of residues and safe for consumption.
Rapid tests
To address this, a series of rapid tests have been developed that can function as a screening test. They are offering a quick answer for the presence or absence of a few antibiotic groups, thus enabling efficient decision-making on whether to accept or reject the milk.
Using the rapid tests, farmers can cost-effectively determine whether milk from animals treated with antibiotics can be delivered to the dairy. If the milk was not tested at the farm, then the dairies are testing it before unloading the truck at the entrance of the plant. Until the milk is proven to be free from any antibiotic residues, it can not be cleared. It is an unwanted risk for the dairies to accept a tank of milk without the confirmation that it is clean of drugs. At the same time, waiting for a couple of hours is a time-consuming and costly business.
Tests for antibiotics
The rapid antibiotic screening test solutions answer to the needs for time-efficiency, safety, and smooth production process. Using Chr. Hansen’s, now Novonesis, rapid tests allow the dairies can quickly have ready, long-lasting, and clearly visible results. They are providing the farmers, producers, and consumers with greater security. This easy-to-use format has wide acceptance in the international dairy market.
