Analytical Report - Muesli - mycotoxins

Mycotoxins are toxic chemicals produced by some moulds which grow on poorly stored crops such as grains and nuts. Two of the most common mycotoxins are aflatoxin and ochratoxin, which can be found in cereals. However, just because the mould is present does not mean than the toxin they can produce will be. Poor storage in hot humid conditions increases the chance of the toxins being produced. Similarly because the mould is not visible to the eye does not mean that the toxin isn’t present. Analysis is therefore needed to check how much if any of these toxins are in the food.

As there are concerns with the dangers to health e.g. cancer and kidney poisoning from eating mycotoxins, samples of muesli were submitted for testing by Kent Trading Standards as part of a project conducted by Hampshire and Kent Scientific Services. Muesli is increasingly popular being regarded as a healthy and nutritious breakfast option.

Twenty samples taken from various supermarkets were sent for testing by Kent Trading Standards. In total 67 samples were submitted by trading standards authorities.

Summary of results

None of the samples were found to contain aflatoxin. Seven sample including 3 from Kent had detectable levels of ochratoxin but the levels were all  below the maximum levels set in The Contaminants in Food Regulations 2006.
