Foodborne diseases (FBD) present high prevalence worldwide and more than 250 types have been reported. The main agents are Staphylococcus aureus, Escherichia coli, Salmonella and certain parasites. The habit of consuming foods sold in street markets in the city of São Paulo exposes consumers to the risk of acquiring FBD. 25 samples of vinaigrette salad were collected in the central, northern, southern, eastern and western regions of the city of São Paulo, Brazil. The samples were inoculated in selective, enriched culture media and biochemical analyses were performed. Bacterial and fungal growth occurred in all samples. The microorganisms detected were E. coli (64%), Enterobacter (60%), S. aureus (52%), Klebsiella (40%), Proteus sp. (32%), Shigella sp. (28%), Citrobacter sp. (16%), Edwardsiella sp. (12%), Alcaligenes sp. (8%), Serratia sp. (8%), Salmonella sp. (4%), Pseudomonas sp. (4%) and; 72% were positive for aflatoxins. Twelve species were identified, 50% of which can cause FBD. S. aureus and fecal coliforms can cause FBD, while Alcaligenes sp. can cause nosocomial infections and Edwardsiella sp. can cause hepatic abscess, meningitis and septicemia. Aflatoxins may cause mycotoxicoses and liver cancer. Therefore, inspections, and prevention and awareness measures should be reinforced to minimize the risks of contracting FBD from foods sold in street markets in the city of São Paulo.

Incidence of enterotoxigenic Escherichia coli (ETEC) in foods usually consumed in the city of Sao Paulo, Brazil was determined. Raw and cooked foods of animal and vegetable origin were investigated. Enterotoxigenic strains were found in approximately 3.5% of food samples contaminated with E. coli. There was a great predominance of ETEC strains producing only LT enterotoxin. None of the isolated strains produced LT and ST simultaneously. Several serotypes were involved, and none of them was positive for colonization factors CFA-I and CFA-II. One ETEC showed resistance to some antibiotics but most were sensitive to the ones tested.

Introduction: Daily and outbursts mortality composting have been identified as one of the finest methods for final disposal of animal corpses, but the probable threat of pathogens transmission truly limits its use. Materials and Methods:  In this study we evaluated the quality and microbiological biosafety of a compost produced in daily mortality experimental unit composting at the Universidade Estadual Paulista in the state of Sao Paulo, Brazil. Settled compost sample was evaluated in order to determine the presence and counting of coliforms and Salmonella sp. and the pathotypes of E. coli STEC, EPEC and EHEC using culture and molecular techniques.  The occurrence of frequent soil borne phytopathogenic fungi was also estimated using selective and differential microbiological culture media. Results and Discussion: The occurrence of pathogenic E. coli, Salmonella sp and phytopathogenic fungi were negative. Coliforms level was 3.05 log10/g. Concussions: The results showed that daily mortality composting method is effective to reduce pathogenic microorganisms, however, in order to add the product on crops or plants such as vegetables that are for direct human consumption, additional tests must be performed to assess the presence of viral pathogens and endospores forming bacteria.

Background: In light of the few reports from intertropical latitudes and their conflicting results, we aimed to replicate and update the investigation of seasonal patterns of suicide occurrences in the city of São Paulo, Brazil. Methods: Data relating to male and female suicides were extracted from the Mortality Information Enhancement Program (PRO-AIM), the official health statistics of the municipality of São Paulo. Seasonality was assessed by studying distribution of suicides over time using cosinor analyses. Results: There were 6,916 registered suicides (76.7% men), with an average of 39.0 ± 7.0 observed suicides per month. For the total sample and for both sexes, cosinor analysis estimated a significant seasonal pattern. For the total sample and for males suicide peaked in November (late spring) with a trough in May–June (late autumn). For females, the estimated peak occurred in January, and the trough in June–July. Conclusions: A seasonal pattern of suicides was found for both males and females, peaking in spring/summer and dipping in fall/winter. The scarcity of reports from intertropical latitudes warrants promoting more studies in this area.

During the initial months of the COVID-19 pandemic, farmers worldwide were greatly affected by disruptions in the food chain. In 2020, São Paulo city experienced most of the effects of the pandemic in Brazil, with 15,587 deaths through December 2020. Here, we describe the impacts of COVID-19 on urban agriculture (UA) in São Paulo from April to August 2020. We analyzed two governmental surveys of 2100 farmers from São Paulo state and 148 from São Paulo city and two qualitative surveys of volunteers from ten community gardens and seven urban farmers. Our data showed that 50% of the farmers were impacted by the pandemic with drops in sales, especially those that depended on intermediaries. Some farmers in the city adapted to novel sales channels, but 22% claimed that obtaining inputs became difficult. No municipal support was provided to UA in São Paulo, and pre-existing issues were exacerbated. Work on community gardens decreased, but no garden permanently closed. Post COVID-19, UA will have the challenge of maintaining local food chains established during the pandemic. Due to the increase in the price of inputs and the lack of technical assistance, governmental efforts should be implemented to support UA.
