Got Milk? Maybe Better Not to in Bogota?

Here is the abstract of a study done on aflatoxin contamination of milk in Bogota conducted by G. J. Diaz of the Laboratorio de Toxicología, Departamento de Ciencias para la Salud Animal, Facultad de Medicina Veterinaria y de Zootecnia, Universidad Nacional de Colombia in Bogota.

"A study was conducted to establish the occurrence and levels of contamination of aflatoxin M 1 (AFM1) in retail milk from Bogotá, Colombia. A total of 241 samples were analysed during 2004 and 2005. Samples were cleaned up by an immunoaffinity column and AFM1 was quantified by liquid chromatography with fluorescence detection. A total of 69.2 and 79.4% of the samples analysed during 2004 and 2005, respectively, were found to contain levels of AFM1 above 10?ng?l -1 . Levels of contamination ranged from 10.7 to 213.0?ng?l -1 in 2004, and from 10.6 to 288.9?ng?l -1 in 2005. Despite the high incidence of AFM1 found in the milk samples analysed, all samples complied with current local regulations, which allow AFM1 content in milk up to 400?ng?l -1 . However, due to the high incidence of AFM1 in milk found in the present study, it is recommended that a permanent surveillance programme be established for milk consumed in Bogotá in order to prevent milk lots containing?levels above the regulatory level entering the food chain."

Platano Caution! It is truth that you post a number of positive episodes about Colombia, but there is also the fact that you also post stories without merit.
When a positive news is broadcasted any where, in particular in Colombia, you have to investigate further the facts related to the story, or wait several days before posting the negative or positive comment to confirm the details!
Examples of articles in haste: The jumbo shrimp, Mundial 2014 although this is great news! The world cup 2014 in Colombia depends on Brazil since they have already requested it back several years ago, and there are other stories I cannot recall at this time.
Question, From where do you get this source? "SOURCE: Occurrence of aflatoxin M 1 in retail milk samples from Bogotá, Colombia. Food Additives & Contaminants; Aug2006, Vol. 23 Issue 8"

Monpirri, my source is impeccable and authoritative... The journal I am citing now has a 2005 impact factor of 1.610 (Copyright ISI Journal Citation Report 2006... ISI is the Institute for Scientific Information) The journal is a tier one world-class peer-reviewed scientific publication and is published in affiliation with the International Society for Mycotoxicology.

Diaz, the author, is a world class Colombian scientist who works with the Laboratorio de Toxicología, Departamento de Ciencias para la Salud Animal, Facultad de Medicina Veterinaria y de Zootecnia, Universidad Nacional de Colombia in Bogota

Diaz published in the Journal Food Additives and Contaminants which publishes original research papers and critical reviews covering analytical methodology, occurrence, persistence, safety evaluation, detoxification, regulatory control, and surveillance of natural and man-made additives and contaminants in the food and animal feed chain.

Papers are published in the areas of pesticide and veterinary drug residues, environmental contaminants, natural toxicants, mycotoxins, trace elements, migration from food packaging, food processing contaminants, authenticity and allergenicity of foods. Papers are published on animal feeds where residues and contaminants can give rise to food safety concerns.

Contributions cover chemistry, biochemistry and bioavailability of these substances, factors affecting levels during production, processing, packaging and storage; the development of novel foods and processes; exposure and risk assessment.

I Thought... Sr. Díaz's report,"Efecto del ensilaje de vísceras de trucha (Oncorhynchus mykiss) sobre el comportamiento productivo y el contenido de ácidos omega-3 en hígado, muslos y pechuga, de pollos de engorde" (Effect of ensiled trout (Oncorhynchus mykiss) intestines on productive traits of broiler chickens and the content of omega-3 fatty acids in liver, thighs and breast." was much more interesting.

Monpirri, It is not available on the internet since it is a subscription journal... it is available in university research libraries in print... or online if you want to pay an exorbitant fee.

In university library? online with exorbitant fee? So only few have access to this privilege information?
What it is the name of the Journal?? Online, the fee is exorbitant? What it's the name of the site? Can anyone check the info on a local library?
I do not trust this type of info that’s why I want to read more about it.

Great information. But what the hell does that mean? Is AFM1 bad? What does it do?

Monpirri, The article is available to anyone. The journal name is Food Additives & Contaminants; (Aug2006, Vol. 23 Issue 8). You may be able to get it free through interlibrary loan in the USA.

The article can be purchased for $38.67 here: http://www.ingentaconnect.com/content/tandf/tfac/2006/00000023/00000008/art00005

For my budget $38.67 plus tax is exorbitant!

Cows in Colombia generally are free range and eat fresh grass, NOT grain or corn.

My gf was considering being a silent partner on a dairy farm earlier in the year, and went on some tours of facilities. They actually had to FIND the cows to milk them, which is how it should be.

For the record, she INSISTED on buying Alpina every time we bought milk. I guess now I know why :P
