“…The percentage of diet samples contaminated above the limits established by legislation in H1 and H2 (25.0 and 27.5%, respectively) were higher than those presented by Lima et al (2005), who found 20.0% of samples contaminated, ranging from 1.1 ¥ 10 3 to 7.4 ¥ 10 4 cfu/mL, and higher than the results presented by Simon et al (2007), who found 16.2% of samples in violation of legislation. Oliveira et al (2000) showed that the counts of mesophilic aerobic microorganisms in enteral diet samples analyzed from a hospital in Florianopolis, Brazil were higher than 10 4 cfu/mL.…”

This work aimed to evaluate the microbiological conditions of enteral feeding, water, powder module and personnel samples obtained from two public hospitals in Goiânia/GO, Brazil. The Escherichia coli and Staphylococcus aureus strains isolated were submitted to antibiogram for phenotypic characterization. The S. aureus strains isolated were grouped into six phenotypic profiles (A–F). There was no correlation among strains isolated from diet and handlers samples. The E. coli strains were grouped into four phenotypic profiles (A–D). The E. coli phenotypes A and C showed the same susceptibility profile for microorganisms isolated from handlers and diets, suggesting a relationship among those isolates. Seven S. aureus and 12 E. coli isolates were resistant to two or more antibiotics. The diets presented unsatisfactory sanitary‐hygienic conditions in the hospitals evaluated because 47 samples (58.8%) from the first hospital and 30 samples (37.5%) from the second hospital were above the limits established by Brazilian legislation. PRACTICAL APPLICATIONS Enteral nutrition is a very important mechanism to provide support to health‐compromised patients, so the microbiological quality of this product is essential to guarantee its safety. This study emphasizes the importance of monitoring the enteral diet microbiological quality and the factors associated with its contamination. The study highlights the use of antibiogram as an instrument to correlate strains in order to help the identification of the probable origin of final product contamination.

Context The safety of enteral formulas is important to restore and maintain the health of patients. Objective A systematic review of the literature was conducted to assess the microbiological contamination present in enteral tube feeding prepared in hospitals and/or at home. Data sources A systematic search was conducted of the Medline, Scopus, BVS, CAPES/MEC, Embase, Science Direct, and SciELO databases and gray literature. Data extraction Eligible studies that analyzed the contamination of enteral formulas manipulated in hospitals and/or at home were selected; a quality assessment tool was used. Data analysis Twenty-three studies evaluated 1099 enteral formulations. Of these, 44.67% of enteral formulas (n = 491) exceeded the acceptable bacterial count. Samples of homemade enteral formulation preparations (86.03%; n = 191) had the highest bacterial counts, followed by mixed preparations (79.72%; n = 59), and commercial formulas (30.01%; n = 241). The number of samples of enteral formulations that exceeded the bacterial count at home was 70.79% (n = 160 at the hospital was 37.91% (n = 331). Total coliforms (82.68%; n = 406) and mesophilic aerobes (79.22%; n = 389) were the most common microorganisms. Samples with bacterial pathogens were also identified, with Bacillus cereus (4.07%; n = 20) and Listeria monocytogenes (3.66%; n = 18) being the most prevalent. Conclusions A high number of samples of enteral formulations exceeded the bacterial count, but the risk to patient’s health when consuming enteral tube feeding prepared in hospitals or at home may be low. This is because the bacteria present in the samples are not considered potential causes of disease but rather indicators of hygiene conditions.

Contamination of enteral diets represents a high risk of compromising the patient's medical condition. To assess the microbiological quality and aseptic conditions in the preparation and administration of handmade and industrialized enteral diets offered in a hospital in the Valley of Jequitinhonha, MG, Brazil, we performed a microbiological analysis of 50 samples of diets and 27 samples of surfaces, utensils, and water used in the preparation of the diets. In addition, we assessed the good handling practices of enteral diets according to the requirements specified by the Brazilian legislation. Both kinds of enteral diets showed contamination by coliforms and Pseudomonas spp. No sample was positive for Staphylococcus aureus and Salmonella spp. On the other hand, Listeria spp. was detected in only one sample of handmade diets. Contamination was significantly higher in the handmade preparations (p < 0.05). Nonconformities were detected with respect to good handling practices, which may compromise the diet safety. The results indicate that the sanitary quality of the enteral diets is unsatisfactory, especially handmade diets. Contamination by Pseudomonas spp. is significant because it is often involved in infection episodes. With regard to aseptic practices, it was observed the need of implementing new procedures for handling enteral diets.
