Context. Dry-aged beef is a value-added product with a unique flavour. The effects of the dry aging process, in terms of chamber temperature and aging time, have not been described previously for Bos indicus meat. Aims. This study evaluated the effects of aging conditions (method, temperature, time) on the microbiological, physicochemical, volatile compound profile and weight loss characteristics of dry-aged and wet-aged beef from Nellore cattle (Bos indicus). Methods. Beef loins (n = 16) were cut into eight portions and assigned to treatments in a complete block design combining aging method (dry or wet), temperature (2 C or 7 C) and time (21 or 42 days). Key results. Samples dry-aged at 7 C had higher (P < 0.05) weight loss than samples dry-aged at 2 C. Although storage temperature did not affect (P > 0.05) the yield of wet-aged samples, Enterobacteriaceae counts increased (P < 0.05) in the samples stored at 7 C compared with 2 C. Aging for 42 days resulted in greater (P < 0.05) process losses (drip + evaporation + trimming) for both aging methods than aging for 21 days. The pH, moisture content and Warner–Bratzler shear force values were not affected (P > 0.05) by aging method, temperature or time. Qualitative analysis indicated that volatile compounds were affected by aging method and time, but not by aging temperature. Conclusions. The results indicate that higher temperature and longer aging periods cannot be not recommended for either dry or wet aging, owing to the increase in process losses of dry-aged samples, and growth of Enterobacteriaceae and psychrotrophic bacteria in wet-aged samples. Implications. This study highlights the importance of controlling conditions for dry aging to produce a safe product and obtain higher yields. Processing plants or retailers that produce dry-aged or wet-aged meat could use these results to adjust their production systems. MenosContext.

Foi realizado um levantamento da infecção por Leptospira spp. em mamíferos silvestres do Pantanal sul-matogrossense com o emprego da reação de soroaglutinação microscópica (SAM) e da reação em cadeia da polimerase (PCR). Os sorovares de maior frequência nos animais investigados foram Hardjobovis (28%), Icterohemorhagiae (12%), M-110/2006 (isolado de Cerdocyon thous; 16%), Canicola (L014 isolada de Bos taurus, 4%), Whitcombi (4%), Pomona (20%), Autumnalis (12%) e Copenhageni (M9/99 isolada de Rattus norvegicus, 4%). Das 79 amostras examinadas pela PCR, 21 (26,58%) foram positivas, com a amplificação de um fragmento de aproximadamente 331pb. Dois fragmentos amplificados obtidos de amostras de C. thous foram clonados, sequenciados e identificados como L. interrogans por análise filogenética. A survey of Leptospira spp. in wild mammals from the southern Pantanal of Mato Grosso do Sul was performed by microscopic agglutination test (MAT) and polymerase chain reaction (PCR). The serovars most frequently found were Hardjobovis (28%), Icterohemorhagiae (12%), M110/2006 strain (isolated from Cerdocyon thous, 16%), Canicola (L014 isolated from Bos Taurus, 4%), Whitcombi (4%), Pomona (20%), Autumnalis (12%) and Copenhageni (M9/99 isolated from Rattus norvegicus, 4%). From the 79 samples tested by PCR, 21 (26.58%) were positive, resulting in the amplification fragment of approximately 331pb. Two amplified fragments from C. thous were cloned, sequenced and identified as L. interrogans by phylogenetic analysis.
