Managing salts while irrigating with wastewater by Qadir, Manzoor, Drechsel, Pay

“…Since saline wastewater can also contain other contaminants than salts it is different from saline drainage or groundwater, and its long-term irrigation may result in the movement of, for example, nitrates, metal ions and metalloids to groundwater. …”

Food safety in developing countries: An overview by Grace, Delia

“…Foodborne diseases (FBD) can be defined as any illness caused by ingesting contaminated food or drink. The most common clinical presentation of foodborne diseases is gastrointestinal symptoms, but foodborne diseases can also lead to chronic, life-threatening symptoms including neurological, gynaecological or immunological disorders as well as multi-organ failure, cancer and death. …”

Identification and molecular analysis of antimicrobial resistant Salmonella isolates obtained from pigs slaughtered at Wambizzi abattoir in Uganda by Tinega, G.M.

“…The results also offer general and rapid approaches for identifying genetic diversity of Salmonella serotypes in individual pig carcasses which can be adopted for molecular epidemiological surveys of important food contaminating bacterial pathogens. Based on these results, it will be important to carry out a similar study in Kenya in order to evaluate food safety issues related to consumption of animal source foods particularly pigs. …”

Functional traits and performance of woody species on oil- affected soils of the Ecuadorian Amazon by Villancis, Jaime, Casanoves, Fernando, Hang, Susana, Armas, Cristina

“…According to Guevara-Andino et al. (2019) in the Ecuadorian Amazon rainforest there are 2296 tree species; however, approximately 4.2 million hectares of this ecosystem have been impacted by many anthropogenic activities related to oil extraction (opening of new roads, construction of platforms, mud and drill cutting cells, contaminated soil treatment units, and settlement of camps and heliports) (Rivera-Parra et al., 2020). …”

How to improve the soilless cultivation of sweet basil looking at light and nutrition? by Säll, Hedvig

“…The EO estragole, with antimicrobial properties, was found in high concentrations in a contaminated farming system. Estragole levels could be practically enforced as indicators of pollutants in the cultivation environment when growing sweet basil.…”

Analysis of preharvest meteorological conditions in relation to concentration of fumonisins in kernels of two genetically different maize hybrids by Moschini, Ricardo Carlos, Borsarelli, Mario, Martinez, Malvina Irene, Presello, Daniel Alberto, Ferraguti, Facundo Javier, Cristos, Diego Sebastian, Rojas, Dante Emanuel

“…Considering the effect of genetic divergence of the two maize hybrids, total kernel FB concentrations (n = 52) binary coded, were predicted appropriately by weather-based logistic regression models but underestimated in some samples severely contaminated with FB. After removing these misclassified cases that registered maximum values of a drought-heat stress index (DI) calculated over 30 days around Si, and weather conditions (assessed by weather interactive components) conducive to infection/production of FB in PM, new logistic models were fitted. …”

Campylobacter jejuni stimulates a robust cytokine response in the cecal tonsil following a repeated challenge infection model by Swaggerty, Christina L., Velilla, Alejandra Vanesa, Genovese, Kenneth J., Allen Byrd, J., Kogut, Michael H.

“…Poultry are known reservoirs, and in many instances, Campylobacter are thought to be commensal organisms harmlessly residing in the gastrointestinal tract of poultry; therefore, human illness could result from mishan dling or consuming raw or undercooked chicken products contaminated with Campylobacter. The objective of this study was to prime the chickens with a low dose of C. jejuni at a young age followed by a higher dose later and monitor changes to key inflammatory and regulatory cytokines and chemokines. …”
