在60日龄和1岁的河豚养殖标本的肠道中检出少量的河豚毒素（TTX），一般认为是无毒的，而在肝脏中未检出毒素。据报道，在培养的红圆梭菌和有毒的野生红圆梭菌的肠道中都存在产生TTX的细菌，这表明肠道中低水平的TTX是由肠道中产生TTX的细菌产生的。另一方面，肝脏中TTX的缺失表明河豚不可能积累低水平的TTX，并在肠道中长期维持。
A small amount of tetrodotoxin (TTX) was identified in the intestine of the cultured puffer Fugu rubripes specimens with ages of 60 days and 1 year old which are generally accepted to be nontoxic, whereas no toxin was detected in the liver. TTX-producing bacteria are reported to occur in the intestine of cultured F. rubripes as well as toxic wild one, suggesting that a low level of TTX in the intestine is produced by the intestinal TTX-producing bacteria. On the other hand, the absence of TTX in the liver indicates that puffer could not accumulate a low level of TTX which is maintained in the intestine for a long period.
