Aflatoxin Contamination: Occurrence and Management

Aflatoxin Contamination: Occurrence and ManagementThomas IsakeitCooperative Extension, The Texas A&M University System

AFLATOXINS: WHAT ARE THEY?- TOXIC CHEMICALS PRODUCED BY FUNGI (Aspergillus flavus and A. parasiticus) GROWING IN CROPS- CAUSE DISEASE IN ANIMALS AND HUMANS (MYCOTOXICOSIS)- MAY BE PRODUCED IN THE FIELD OR AFTER HARVEST- AFFECT MANY TYPES OF CROPS

TYPES OF AFLATOXINSSTRUCTURE OF B1, THE MOST POTENT AFLATOXIN, SPECIFICALLY REGULATED IN SOME COUNTRIESALSO: B2, G1 AND G2 M1 AND M2 IN MILK: SPECIFICALLY REGULATED

AFLATOXIN TOXICITY - HUMANS HEPATIC AND GASTROINTESTINAL INJURY IMMUNOSUPPRESSIVE TERATOGENIC ONCOGENIC SEVERE LIVER INJURY, SOMETIMES FATAL (2-6 MG/DAY FOR A MONTH)

AFLATOXIN TOXICITY - ANIMALSLUNG LESIONS IN A PIG POISONED BY AFLATOXIN VARIOUS SYMPTOMS: FROM REDUCED GAIN TO DEATH VARYING SENSITIVITY AMONG SPECIES

AFLATOXIN POISONING FROM CORN RECENT CASES TEXAS, 1998: 25 DOGS DIED 100-200 PPB, FULL DIET FOR 90 DAYS KENYA, 2004: 125 PEOPLE DIED, 192 POISONED DAMP STORAGE OF CORN, UP TO 8,000 PPB

LOSS FROM AFLATOXIN IN TEXAS CORN IN 1998 YIELD LOSS FROM DROUGHT PRICE DROP ($2.20/BU vs. $2.80) $407 MILLION VALUE W/O TOXIN 18 31% CROP CONTAMINATION TOXIN VALUE: $1.30 - $1.40 / BU$17 - $40 MILLION LOSS

HISTORY IN TEXASAFLATOXIN?LOSING TURKEYS: I CUT THEM OPEN AFTER THEY DIE AND FIND A BIG LIGHT COLLORD LIVER; THE GIZZARD IS ENLARGED, ALSO THE GALL IS TWICE AS LARGE AS SHOULD BE. - LETTER TO FARM AND RANCH, MAY 19, 1917 FROM VAN ZANDT COUNTY, TX

HISTORY IN TEXASJ.J. Taubenhaus documents A. flavus as a pathogen

A. FLAVUS IS A WEAK PATHOGEN THAT DOES NOT ALWAYS PRODUCE SYMPTOMSASPERGILLUS EAR ROT

CONSEQUENTLY, AFLATOXIN DETECTION REQUIRES A CHEMICAL ANALYSISEXTRACTIONPURIFICATIONANALYSISDETECTION IS DIFFICULT!

SAMPLING IS MORE DIFFICULT!CONTAMINATION IS NOT UNIFORM:- WITHIN A REGION - WITHIN A FIELD- ON A PLANT- WITHIN AN EAR- WITHIN A SEED

AFLATOXIN DISTRIBUTION IN TEXAS2002 CORN ACREAGE2003 CONTAMINATION

COMPILED BY: OFFICE OF THE TEXAS STATE CHEMIST

AFLATOXIN IN AN EAR OF CORNCONCENTRATIONS ARE DIFFERENT FOR EACH KERNEL

WHERE AFLATOXIN OCCURS IN A CORN SEED (SHOWN IN RED)AS SHOWN BY THE RED COLOR MUTANT, AFLATOXIN IS FOUND IN THE ALEURONE

A SMALL PROPORTION OF CORN IS HIGHLY CONTAMINATED:1 KERNEL WITH 400,000 PPB WILL MAKE A 10-LB SAMPLE MEASURE 26 PPB
