Ochratoxin contamination in pig feed from pig farming centres in Indonesia

Ochratoxin A (OTA) is the most common toxin found in nature. Ochratoxin is a metabolic product by Aspergillus spp. and Penicillium spp. OTA produced by many Aspergillus or Penicicillium species that contaminate animal feeds can cause diseases. This study aims to determine the incidence of ochratoxin contamination in pig feed such as pellets, meat bone meal (MBM), and tofu by products. The sampling method used the disease detection formula to collect 36 samples 36 taken from several regions. North Sumatra, East Nusa Tenggara, Bali, Bulan Island, Solo, Lampung, Banten, Bogor and Jakarta. Ochratoxin contamination in animal feed was detected based on the Enzyme Linked Immunosorbent Assay (ELISA) using Agraquant® ochratoxin assay following the manufacturer’s protocol. The analysis showed that 6 of the 36 samples (16.7%) were tested positive for ochratoxin contamination. Pellets and MBM were the feed and feedstuff which were found to contain ochratoxin. The concentration of ochratoxin in MBM was below the limit set by the National Agency of Drug and Food Control of the Republic of Indonesia (5 ppb). The high contamination of ochratoxin was found in pellets from Lampung (19 ppb). The fungi found to dominates the culture media and come from pellet feed were Aspergillus flavus and Aspergillus niger.
