The screening of hundreds of substances belonging to multiple chemical classes in liver is required in areas such as food safety or biomonitoring. We adapted a previous QuEChERS-based method in blood to the liver matrix and applied to these fields of study. The validation of the method allowed the inclusion of 351 contaminants, 80% with a LOQ < 2 ng/g. In the analysis of 42 consumer liver samples, we detected trace levels of 29 different contaminants. The most frequent and concentrated was 4,4’-DDE. POPs accounted for 66% of the compounds detected. In no case was the MRL reached for any of the contaminants detected. We also applied the method to 151 livers of wild birds to perform a biomonitoring pilot study in the Canary Islands. We detected 52 contaminants in 15 bird species. These were also mostly POPs, although high frequencies and concentrations of anticoagulant rodenticides (AR) and some other agricultural pesticides also stand out. POPs and AR contamination levels were significantly higher in terrestrial birds, raptors and particularly in nocturnal birds. Pesticide contamination levels were also higher in terrestrial birds, as well as in non-raptors and diurnal birds. The validated method is simple, robust, and sensitive and performs well in a variety of practical scenarios, where it can be carried out relatively quickly and inexpensively.

Abstract Some bird species often benefit farmers by suppressing invertebrate crop pests, yet birds are rarely considered in integrated pest management (IPM) strategies. This is likely because some bird species pose risks to farmers through crop damage, intraguild predation, and food safety concerns. Nonetheless, the benefits of some bird species on crop production are often substantial. Therefore, understanding when birds are most likely to enhance crop production (and when they are most likely to depress it) is crucial for designing effective IPM strategies. Here, we briefly review the literature on birds in agricultural systems, discuss examples of how birds can provide services and disservices to crops, examine factors that influence the net effects of birds, and discuss emerging tools that will help fill key knowledge gaps surrounding the complex roles of birds in agricultural systems.

Abstract Background Lead is a heavy metal naturally occurring in the environment and also released by some anthropogenic activities. Food is one the major sources of human exposure for non-occupationally exposed individuals. In this study, we aimed at characterizing lead (Pb) content in foods consumed in Northern Italy population, in order to estimate its dietary intake. Methods We measured lead content in 908 food and beverage samples bought at small shops and supermarkets of the Northern Italy provinces of Modena and Reggio Emilia, through inductively coupled plasma mass spectrometry. We used a validated semi-quantitative food frequency questionnaire to assess the dietary habits of a representative sample of 719 individuals (319 males and 400 females) aged 18-87 years residing in Northern Italy (Emilia Romagna). We estimated weekly dietary intakes of Pb, and we compared them with safety standards set by the European Food Safety Authority (EFSA). Results In this population, vegetables and vegetables products were the main contributors to Pb intake. The highest levels of Pb were in edible offal, and then in crustaceans, dry fruits, chocolate free sweet confectionery, and coffee and tea as beverages. In general, Pb levels in our samples were comparable and did not exceed the average contamination levels reported by EFSA in various European countries. We found a comparable average Pb intake in both sexes. Average weekly intake of Pb was below EFSA recommended provisional tolerable weekly intake. Conclusions Our study provides an updated assessment of lead exposure through diet in a Northern Italian community. Although environmental lead contamination and exposure have markedly decreased in the last decades, recent evidence pointed out that a safety threshold value cannot yet be established for prevention of adverse effects due to lead exposure, since even low levels of lead intake may still increase the risk of chronic renal disease and hypertension. Key messages Food is one the major lead sources of human exposure for non-occupationally exposed individuals. Lead levels in Northern Italian population studied are comparable and do not exceed the average contamination levels reported by European Food Safety Authority in various European countries.

Contamination Levels

Processed meat products are commonplace foods that are becoming increasingly popular in consumers' daily diets. Therefore, it is highly essential to assess the extent of microbiological contamination in the samples of processed meat products from markets in a bid to provide updated data of microbiological contamination to relevant agencies and local consumers as part of the current state of food safety and hygiene in the locality. A survey on microbiological contamination of processed meat products was conducted on samples collected from some markets in Southern Hue city. The 90 samples of three groups of fermented meat, packaged and non-packaged meat were analyzed. The results showed that, 100% of the samples were contaminated with aerobic microorganisms, Coliforms and Escherichia coli, in which 100% of the samples of Coliforms and E. coli did not meet the quality norms set by the Ministry of Health. The total aerobic microorganisms, Coliforms and E. coli ranged from 2.7 &times; 103 to 2.8 &times; 109 CFU/g, 1.1 &times; 104 to 1.5 &times; 108 MPN/g and 1.1 &times; 102 to 9.2 &times; 105 MPN/g, respectively. No presence of Clostridium perfringens or Staphylococcus aureus was detected in the examined samples.

Antisepsis of the skin of children to whom a peripheral venous catheter (PVC) is to be attached is an important factor in reducing catheter related infections. No data are available on the effectiveness of sodium hypochlorite. Explorative study of children and new-born babies treated in hospital to ascertain bacterial contamination levels of PVC tips as surrogate infection indicator. In a sample of 51 children and 52 new-born babies, catheter tips were found contaminated for 7.8% of the children and 3.8% of the new-born babies. The positive results of this pilot study suggest that serious consideration should be given to assessing Amukine Med 0.05% for use with PVCs.
