Excessive Copper Levels in Cooked Sausages: A Case Study of Local Market Products

This study aimed to assess the presence of heavy metals, specifically lead, cadmium, mercury, copper, and zinc in locally sourced sausage products, both cooked and semi-smoked. A total of 30 samples were selected from local markets and subjected to atomic absorption spectrometry for precise metal quantification. Our results indicated that the concentration of zinc (18.36 mg/kg), mercury (0.01 mg/kg), lead (0.24 mg/kg), and cadmium (0.02 mg/kg) in cooked sausage products adhered to the maximum allowable concentration (MAC) guidelines as stated by the TR TS 021/2011 “Hygienic requirements for safety and food value of food products”. However, the copper content in cooked sausages was found to be above the MAC at an average of 1.44 mg/kg, suggesting potential food safety concerns. Semi-smoked sausages, on the other hand, had no recorded heavy metal concentrations exceeding the MAC. The findings of this study are significant, underscoring the need for robust and rigorous monitoring of food products for heavy metals, especially copper, to ensure public health and safety

Fish-breeding-biological and productional characteristic of reproductive peculiar properties of crucian and gold carp breeders and their's hybrids

The reproductive characteristics of crucian carp producers, the growth of hybrids and pure types in the embryonic and postembryonic period have been studied. The valuation of crucian carp has been done, that allowed them to be attributed to the first class. It was found that some differences on the exterior were observed on the volume of ejaculate, and on the working absolute fecundity of crucian carp. These indicators were higher in silver crucian carp than gold crucian carp. Breeding performance had great influence on the development of the young crucian carp types. Hybrid young crucian carp fry had higher weight than pure types of crucian carp that live in ponds with different feeding conditions
