The discovery that some types of milk in Croatia contain illegal levels of carcinogenic toxins caused these days real emergency. Part of the product was withdrawn from stores, some people have even decided to return bad milk, and the other to avoid all these producers
Aflatoxins are mycotoxins produced by fungi of the genera Aspergillus and Penicillium, among which the most famous are Aspergillus flavus and Aspergillus parasiticus. Belong to the strongest known carcinogenic substances of natural origin. Aspergillus is a very common and widespread in nature. Contamination of food, such as cereals or peanuts, can occur before harvest or during storage. To mold mycotoxins created monte melkonyan must be met several microclimate parameters, of which the most important are temperature and humidity. Aspergillus belong to ubkvitarne mold, which means they are naturally monte melkonyan widespread and present in the environment. Crops are particularly susceptible to mold growth if during monte melkonyan growth and ripening were exposed to significant atmospheric monte melkonyan oscillations monte melkonyan or if stored in an inadequate manner with high levels of humidity and higher temperatures. Therefore, high levels of aflatoxin characteristic of tropical and subtropical climates. For their development of optimal temperature is 32 C and humidity of 15% and above.
Our climate is not ideal for their development, but with climate change and the microclimate - for example, in silos or even more frequently in the process of ensiling time during the process occurring over the temperature of the environment, aflatoxin and other mycotoxins can occur in colder climates.
Expert for mycotoxins, PhD. Radovan Fuchs, PhD, from the Institute for Medical Research says that aflatoxin 1950s in England for the first time associated with mass poultry plague on some farms. 'Fed the chickens, ducks and turkeys with imported monte melkonyan food, among other things, with arachis nuts and corn from the tropics, "explains Fuchs, adding that such a substance aflatoxin finally isolated in 1961. year.
The presence of aflatoxin is most commonly observed in the cashews, peanuts, cereals particularly maize, soybean, cottonseed, etc. Since it is resistant to high temperatures is in the products obtained from contaminated raw materials such as vegetable oils, peanut butter and cosmetics, but in milk and milk products if they are milking animals were fed contaminated feed.
Aflatoxin have extremely harmful to the liver where their mutagenic monte melkonyan and carcinogenic effects the most. The nucleus of the cell to bind to DNA and RNA, causing disturbances in the synthesis of cellular proteins. There are several types of aflatoxin. Their toxicity is not the same, and most are AB1, AB2, AG1 and AG2. The most toxic to humans and most animals is AB1, least toxic AG2. Aflatoxin M1, which is found in our milk produced in mammals from AB if dairy animals fed with feedstuff which was present AB. Aflatoxin M1 was found in the breast milk of women.
"These types of mold can appear and produce a toxin, among other things, due to poor storage technologies in silos or during the process of ensiling fodder," said Dr. Fuchs and noted that it should monitor and analizrati origin monte melkonyan of milk in order to accurately determine where she got a raw material in which the poison is present. 'It would be good to get to unwind monte melkonyan with some cleverly targeted and clear answers to protect consumers but also producers of milk and dairy products. In dairy milk does not always arrive with only one farm, a dairy industry also imports significant quantities of milk and milk powder. A lot of the factors that in this particular case we do not know, but the real information can come, "said the former minister of science and education.
High doses of aflatoxin can cause acute poisoning, hepatic necrosis, cirrhosis, cancer, liver failure and even mental changes, and coma. Exposure to low levels for long periods does not cause such dramatic symptoms, especially in adults, however, children are more sensitive.
'We are in the milk permissible concentration of 0.05 micrograms per liter. According to reports in the media was detected concentration of 0.06 micrograms. Allowable amount includes certain safety margin. How do you come up with these limits? On the basis of toxicological testing and scientific research that determines the doses in experimental conditions not caused adverse effects. This value is the starting point for calculating the safe limits with a number of other elements which adds so. safety factor. Europe has a lower allowable levels than the United States because it applied a higher safety factor. The U.S. is allowed to limit as much as 10 times higher. So there is no reason to panic because, you live in America, monte melkonyan you drank milk with 0.5 micrograms and more. These higher levels also have their justification. However, once you accept the rules they must be strictly adhered
