1. Hazards of Ochratoxin A

1. Strong nephrotoxicity and hepatotoxicity

   OTA mainly damages the kidneys and liver, causing organ swelling, necrosis and dysfunction. Long-term exposure leads to chronic poisoning.

2. Carcinogenic, teratogenic and genotoxic effects

   Classified as Group 2B carcinogen by IARC, OTA has significant teratogenic and genotoxic risks to animals and humans.

3. Immunosuppression and growth inhibition

   It suppresses immune function, reduces disease resistance, and causes slow growth and poor reproductive performance in livestock.

4. Food chain contamination

   OTA can transfer into meat, eggs and milk through cereals and feed, endangering human health.
