Metal levels in fodder, milk, dairy products, and tissues sampled in ovine farms of Southern Italy

AbstractThis study was conducted to determine heavy metals concentrations in tissues of 94 birds belonging to different species from coastal areas of Naples and Salerno (Southern Italy) in order to provide baseline data concerning trace element levels in wild birds living in or close to an area characterized by high anthropogenic impact. Additional aim of this study was to verify if diet influenced metal accumulation, so birds were classified as birds of prey, fish eating birds and insectivorous birds. Kidney was the primary organ for Cd accumulation in all groups considered, Pb was accumulated preferentially in bone, whereas Hg showed high values in liver of fish eating birds. Zn showed the highest mean concentrations, while Cu levels were one order of magnitude less. The variance analysis with respect to feeding habits disclosed only a lower accumulation of Hg in insectivores with respect to the other groups. For all metals, the concentrations measured in tissues should be considered indicative of chronic exposure to low, “background” environmental levels and/or to the presence of low bioavailable metals in the environment. In addition, metal levels were not of toxicological concern, being always well below the toxic thresholds defined for each metal.

Pastoral Value

In the Iblei plateau (Sicily, Southern Italy) the native dairy cattle breed Modicana during the spring season grazes exclusively on natural pastures for the production of the Ragusano protected denomination of origin cheese. Along the grazing season, herbage undergoes to changes on protein, fibre and moisture content, affecting quality parameters such as plant carotenoids concentration, involved in the colour and nutritional characteristics of dairy products and potential biomarkers for authenticating fed green pasture-based diets. The aim of this work was to assess whether the cheese traceability index, based on the carotenoids spectra data elaboration, could be related to seasonal variations of floral composition and pasture quality. Four herbage and cheese samples were collected every two weeks in two representative farms of this area, from March to May 2013. Pasture characteristics as pastoral vegetation composition and pastoral value were analysed using the methodology developed for pastoral resources studies. Traceability index showed a significant positive correlation with pasture moisture and crude protein content (r=0.729* and 0.853**, respectively), while it was negatively correlated with fibre content (r=–0.719*).

High Forage

The aim of the present work was to investigate the consumers’ willingness to pay (WTP) for dairy products obtained by grazing animals or fed with a high forage/concentrate ratio diet. To this aim, a survey was carried out on Italian consumers in the Campania Region and data collected were analyzed both by simple descriptive statistics and by an econometric model. Our results highlight that young age, knowledge of milk properties, and a healthy lifestyle are extremely important components in determining a higher WTP.

Conventional Milk

This study aimed to determine and compare aluminum (Al), arsenic (As), cadmium (Cd), and lead (Pb) levels in conventional and organic milk, white cheese, and butter samples which are sold in the markets of Turkey. Within the scope of the study, totally 72 samples (36 for organic, and 36 for conventional) were collected, and analyzed between March 2010 and February 2011. After the samples were burned by microwave burning, element measurements were performed on atomic absorption spectrophotometer (AAS) device. As a result of the study, on the 49 samples (29 conventional, 20 organic) of the 72 collected product, element levels were determined above the limit of detection (LOD) (0.02 ppm). Pb and Al were the most common elements above the LOD. However, milk samples with a Pb level above the LOD still remained below the limit reported by the Turkish Food Codex Regulation for Contaminants. Since Turkish Food Codex Regulation does not have legal limits for Al, As, Cd and Pb for dairy products (cheese and butter), it was accepted as safe in terms of Al, As, Cd and Pb according to food limits in Turkish Food Codex and ADI values of FAO / WHO.
