Smoke produced in cashew processing factories during roasting of the seed
contains toxic chemicals which have adverse health effects on workers exposed
to it. This study investigated the effect of cashew seed fume on lactate
dehydrogenase (LDH) activity, methemoglobin (Hi), carboxyhemoglobin (HbCO) and sulfhemoglobin (SHb) in the blood of rats exposed to cashew seed fumes (CSF), via the dynamic
exposure system. Eighteen (18) male albino rats were used; they were divided into
three groups of six animals each as: control, rats exposed for two (2) hours
and rats exposed four (4) hours for five days. The results showed that serum level
of LDH in rats exposed to CSF was significantly (P < 0.05) increased compared with the control rats. The %SHb and
%HbCO in the blood of rats exposed to CSF were significantly (P < 0.05) increased compared with the
control rats. However there were no significant (P > 0.05) differences in the % methemoglobin level of rats in
all groups. This study revealed that exposure to CSF may have adverse effects
on the lungs and may also result in system poisoning. This should be a cause of
concern for industrial regulatory bodies who should regulate the safety of cashew
