A total of 484 rice samples were collected from five polluted areas in China to investigate the cadmium (Cd) contamination of rice and its potential health risks. The mean Cd contents of analyzed rice samples obtained from different areas ranged from 0.149 to 0.189 mg·kg(-1). Cd concentrations in more than 18% of rice samples exceeded the maximum allowable Cd concentration, and the highest level of 41.1% was observed in samples from Hezhang, Guizhou, which was characterized by serious Cd pollution. Target hazard quotient (THQ) values of 1.5 to 7.8 from rice intake indicated a significant non-carcinogenic health risk for humans, particularly for highly exposed consumers. Children are more at risk than adults, as indicated by the higher THQs. Moreover, carcinogenic risks of Cd from rice intake for average and high consumers in the selected areas were two to three and four to eight greater, respectively, than the threshold value recommended by the International Commission on Radiological Protection.

“…Cadmium is a heavy metal of great concern in agricultural ecosystems because of its high toxicity to animals and human health. Cadmium toxicity especially affects human health rather than plants and animals because of its longevity and the accumulation in organs through the consumption of cadmiumcontaminated foods (Cheng and Gobas, 2007). Chronic exposure to human beings of cadmium through ingestion and/or inhalation results in severe damage to kidneys and lungs and can lead to other pathological symptoms such as itai-itai disease (Nogawa et al, 1983).…”

Aim: To isolate and characterize lactic acid bacteria (LAB) and determine whether they could potentially be used as heavy metal (cadmium and lead) absorbing probiotics. Methods and Results: The study used 53 environmental (mud and sludge) samples to isolate cadmium‐ and lead‐resistant LAB, by following spared plate technique. A total of 255 cadmium‐ and lead‐resistant LAB were isolated from these samples. The survival of 26 of the LAB was found after passing through sequential probiotic characterizations. These 26 probiotic LAB exhibited remarkable variations in their metal‐resistant and metal‐removal abilities. Of 26, seven (Cd54‐2, Cd61‐7, Cd69‐12, Cd70‐13, Pb82‐8, Pb96‐19 and Cd109‐16) and four (Pb71‐1, Pb73‐2, Pb85‐9 and Pb96‐19) strains displayed relatively elevated cadmium‐ and lead‐removal efficiencies from water, respectively, compare with that of the remaining strains. Strains Cd70‐13 and Pb71‐1 showed the highest cadmium (25%) and lead (59%) removal capacity from MRS (De Man, Rogosa and Sharpe) culture medium, respectively, amongst the selected strains and showed a good adhesive ability on fish mucus. A phylogenetic analysis of their 16S rDNA sequences revealed that the strains Cd70‐13 and Pb71‐1 belong to Lactobacillus reuteri. Conclusion: Excellent probiotic, metal sorption and adhesive characteristics of newly identified Lact. reuteri strains Cd70‐13 and Pb71‐1 were isolated, which indicated their high potential abilities to survive in the intestinal milieu and to uptake the tested metals from the environment. Significance and Impact of the Study: To our knowledge, this is the first study that has aimed to isolate, characterize and identify metal‐resistant LAB strains that have potential to be a probiotic candidate for food and in vivo challenge studies in the intestinal milieu of fish for the uptake and control of heavy metal bioaccumulation.
