Preguntas Frecuentes

Las micotoxinas son substancias tóxicas producidas por mohos. No es necesario que haya moho visible en el pienso para que esté contaminado por el contrario el hecho de que haya moho visible en el pienso no significa que haya micotoxinas. Diferentes especies de mohos producen diferentes micotoxinas. Los materiales para las camas, incluyendo la paja, también pueden contener micotoxinas.

Las micotoxinas más prevalentes son las producidas por los mohos AspergillusFusarium que se encuentran de manera natural en el medio ambiente.

Moulds produce mycotoxins as a response to environmental stress conditions.  These are usually related to weather conditions such as temperature and rainfall extremes.  Toxins can be produced while the crop is still in the field and/or after harvesting.  Poor handling and storage conditions can cause further contamination of feeds.  The risk of mycotoxins is always present.

No.  Mycotoxins are produced by living mould organisms, but they themselves are just toxic secretions of these moulds.  The mould may be killed, but any toxins already produced will remain.

There are many different mycotoxins that can cause a variety of effects in animals.  Symptoms will vary depending on the mycotoxin and the species.  Lower levels however tend to result in chronic effects including reduced feed intake, immune suppression, or reproductive issues.  Higher levels can have acute effects including severe organ damage, abortions, and death.  All species can be affected by mycotoxins.  More information can be found here

There are several options for measuring mycotoxins in animal feed.  These range from inexpensive rapid test kits, designed to detect specific toxins in specific commodities, to full screening by accredited laboratories, which can detect a range of mycotoxins in many different sample types.

Rapid test kits have a place if you have a single commodity and you are looking for a specific mycotoxin.  They do not always work well across a range of sample types or in materials where many feed types are present such as compound feed or TMR.

The most accurate and detailed way to test for mycotoxins is to submit samples to an accredited lab using liquid chromatography mass spectrometry.

Mycocheck assigns risk based on the levels of mycotoxins detected in each sample.  For detailed information on risk assignment, please visit our page on risk.

All analytical techniques produce results with an associated confidence interval, known as the measurement uncertainty (MU).  More information on MU can be found on the UKAS website.  For information on how Mycocheck uses MU, visit our page on measurement uncertainty
