Irrigation water has been recognized as an important microbial risk factor for fruits and vegetables in many production areas, but there is still a lack of information about how the microbiological quality different irrigation sources climatic conditions influence safety produced Brazil. This study evaluated distribution generic E. coli prevalence O157:H7 two (ponds streams bordering farmlands urban areas) used on commercially lettuces Southern We also effect agricultural factors...

Abstract An antimicrobial and antioxidant film based on cassava starch incorporated with oregano essential oil (2% w/v) pumpkin residue extract (3% was developed for application onto ground beef. A control (without additives) used comparison. The film's physical, barrier, (DPPH), properties were analyzed. addition of does not contribute to reducing the water vapor permeability or impact solubility values. Regarding beef, demonstrated activity against mesophilic bacteria, coliforms,...

The aim of this study was to assess the risk occurrence a foodborne outbreak and point practices determinant achieve high Good Hygienic Practice level during handling practice from purchase consumption chicken meat eggs. behavior respondents were measured using Weighted Harmonic Outbreak Prevention Index (WHOPI). WHOPI not correlated socioeconomic data perception risks. Different profiles identified inside each level. Chicken defrost, time temperature egg cooking yolk as most important...

Strawberries are an important fruit in Belgium both production and consumption, but little information is available about the presence of Salmonella Shiga toxin-producing Escherichia coli (STEC) these berries, risk factors agricultural production, possible specific mitigation options. In 2012, a survey was undertaken three soil soilless cultivation systems Belgium. No spp. were isolated. STEC detected strawberry samples (0 72), by PCR 11 78 irrigation water 2 24 substrate samples.

Washing and disinfection methods used by minimally processed vegetable industries of Southern Brazil were reproduced in laboratory order to verify their effectiveness reduce Salmonella Enteritidis SE86 (SE86) on lettuce.Among the five investigated, four carried out washing with potable water followed 200 ppm sodium hypochlorite during different immersion times.The procedure alone decreased approximately 1 log CFU/g population times 1, 2, 5, 15 minutes disinfectant solution demonstrated...

Vegetable salads constitute an important component of many meals worldwide. However there is concern for their safety and microbiological quality because they have been implicated in outbreaks foodborne diseases, especially developing countries.
