Rice is a predominant food consumed by more than half of the population in the world. Till date, rice toxins have been predominantly reported as heavy metals such as arsenic, lead or cadmium due to its culture conditions and microbes such as Bacillus cereus or Staphyloccocccus aureus due to its storage conditions; gastric irritations and associated clinical manifestations have been the outcomes of such toxicity. Herein, we have explored the neuropharmacological toxicity of contaminated rice which may be associated with the poor storage of rice feedstock. For example, autoclaving a random sample of contaminated rice at 121ºC at 14 psi pressure for 15 mins, yielded an extract which resulted in reduced locomotor, depression scoring and muscle relaxant activity in healthy Swiss- albino rats. The identification studies advocated the presence of Stenotrophomonas maltophilia, a gram negative bacillus in it; whose cell extract was revealed to induce such altered neuropharmacological behaviour. FAME guided GC-MS analysis of such extract demonstrated that mono and di-unsaturated fatty acids (UFA) such as 18:1 ω 7 c, 16:1 ω 6 c, 16:1 ω 7 c and 18:2 ω 6,9 c long chain fatty acids have been the chief agents probably acting as the toxicants. The in silico analysis revealed binding interactions of UFA with certain bioamine producing enzymes possibly interfering with bioamine production.
