It is primarily responsible for envenomation cases in rural areas, and is often cited as the second most toxic of its kind, behind only T. serrulatus.{{citation needed|date=March 2021}} Its neurotoxic venom causes symptoms such as severe pain, edema, sweating, lethargy, tachycardia, pulmonary edema, dyspnea, pancreatitis, gastrointestinal complications, nausea, vomiting and changes in blood pressure.{{cite web|url=https://www.acq.osd.mil/eie/afpmb/docs/lhd/venomous_animals_byspecies.pdf|title=Living Hazards Database (LHD) – Search by Scientific Name|website=Acq.osd.mil|access-date=14 March 2022}} The LD50 for its venom is 0.5 mg/kg.{{Cite book|last=Flindt|first=Rainer|url=https://books.google.com/books?id=9t7Tht1kf88C&q=ctenus+ferus&pg=PA26|title=Amazing Numbers in Biology|date=2006-12-21|publisher=Springer Science & Business Media|isbn=978-3-540-30147-9|language=en}} The most prevalent toxin found in the venom of T. bahiensis is Tb1, accounting for 10% of the entire soluble venom content. {{Cite journal |last1=Becerril |first1=B. |last2=Corona |first2=M. |last3=Coronas |first3=F.
