One hundred and forty samples of vegetables and 45 samples of irrigation water were investigated for thermotolerant coliforms and Salmonella spp. In order to verify the effectiveness of natural household sanitizers in reducing E. coli in inoculated lettuce, four treatment solutions were tested: fresh lemon juice, alcohol vinegar, lemon juice-vinegar mixture, and lemon juice-vinegar-water mixture. The microbiological analysis revealed high rates of contamination by thermotolerant coliforms and identified the presence of E. coli in 32% of the tested vegetable samples and 56% of the water samples. While no significant statistical difference (p < 0, 05) was identified in the tested solutions, the treatment with a combination of lemon juice and vinegar resulted in the highest Decimal Reductions (DR) of E. coli O157: H7 while the treatment with vinegar alone was the most effective against the indigenous E. coli strain.Submitted by Rigaud Andréa (andrearigaud16@yahoo.com.br) on 2011-09-27T16:51:27Z No. of bitstreams: 1 v30n4a38.pdf: 189089 bytes, checksum: aad6ab36a016fe13ea7f0268305b612d (MD5)Made available in DSpace on 2011-09-27T16:51:27Z (GMT).
