Mesoregion Potiguar West - RN -Brazil meet specifications certain laws. We analyzed 73 samples of honey determining the physical and chemical parameters, qualitative tests (Fiehe, diastatic ferment and Lugol), sensory and microbiological samples were honey collected in the homes of around 500 ml per beekeeper and analyzed 48 collected after each hour. The collection period was from March 2008 to September 2009. The results were the predominant color with 36% of amber light, moisture (20.16% ± 3.44%), water activity (0.620 ± 0.027%), solid (0.329 ± 0.311%), ash (0.146 ± 0.086%), density (1.402 g.cm-1 ± 0.034), pH (3.39 ± 0.49), acidity (38.07 mEq / kg ± 16.45), sugars (63.24 ± 10.25%), sucrose (5.674% ± 1.02), HMF (10.94 mg / kg ± 4.91), Lund (0621 +0.257%) and conductivity (0.356 mS / cm ± 0.125), negative results for the qualitative tests, 18 samples with yeast and mold growth and 15 samples with coliform and total coliforms. The HMF values, acidity, color, ash were in agreement with the regulations of BRAZIL (2000), Codex (2001) and MERCOSUL (GMC 89/99) and conductivity, sugars according to the Codex (2001), 18 samples were values greater than 100 CFU / g for molds and yeasts and 15 had values above <3NMP / g opposing MERCOSUR (GMC 89/99). The characteristics of honey samples produced that do not conform with the standards indicate the need for a revision of these standards and who have the honey microbial growth suggest the application of best practices for beekeeping. / Verificou-se os méis produzidos por Apis mellifera L. na Mesorregião do Oeste Potiguar - RN Brasil cumprem as especificações determinadas pelas legislações. Foram analisadas 73 amostras de mel determinando os parâmetros físico-químicos, testes qualitativos (Fiehe, fermento diastásico e Lugol), sensoriais e microbiológicos, as amostras foram coletadas nas casas de mel, em torno de 500 ml por apicultor e analisadas 48 horas após cada coleta. O período de coleta foi de março de 2008 a setembro 2009. Os resultados obtidos foram: a cor com predominância de 36% de âmbar claro, umidade (20,16%±3,44%), atividade de água (0,620±0,027%), sólidos (0,33±0,311%), cinzas (0,15±0,086%), densidade (1,40g.cm-1±0,034), pH de (3,39±0,49), acidez (38,07 meq/kg±16,45), açúcares (63,24%±10,25), sacarose (5,674%±1,02), HMF (10,94 mg/kg±4,91), Lund (0621+0,257%) e condutividade (0,36 mS/cm±0,125); resultados negativos para os testes qualitativos, 18 amostras com crescimento bolores e leveduras e 15 amostras com coliformes totais e fecais. Os valores HMF, acidez livre, cor, cinzas estiveram de acordo com os regulamentos do BRASIL (2000), Codex (2001) e o MERCOSUL (GMC 89/99) e a condutividade, açúcares de acordo com o Codex (2001); 18 amostras tiveram valores maiores que 100 UFC/g para bolores e leveduras e 15 tiveram valores acima de <3NMP/g contrapondo o MERCOSUL (GMC 89/99). As características das amostras de méis produzidas que não estão em conformidade com as normas indicam a necessidade de reformulação desses padrões e os méis que tiveram crescimento microbiano sugerem a necessidade de aplicação das boas práticas de apícolas.
