Some heavy metals are harmful and dangerous and cause many risks for food and public health. Also accumulated in fish such as tuna fish as a result of contaminated water or during transport, processing or canning. The present study was conducted to measure the concentration of some heavy metals (Pb, Cd, Al, Hg, Ni, Co and Cr) in canned tuna of five brands. Materials and Methods: Forty canned tuna samples from five brands were examined to determine their metal concentration. The samples were collected from supermarkets found in Assiut city (Egypt) from June 2017 to November 2017. The metals were determined using Atomic Absorption Spectrometer Perkin Elymer (Analyst 400) for Pb, Cd, Co, Ni and Cr while Hg was estimated by using ICP (iCAP 6200) and Al was determined using Atomic Absorption Spectrometer (ZEEnit700P). Results: The results revealed that the levels (ppm wet weight) of metals were as following in the examined five brands:

A retrospective study covered the period of 10-year (2000-2010) to investigate the prevalence of hydatidosis in ruminants of three provinces abattoirs in Iraq (Al Muthanna, Al Qadysiah and Al Najaf). A total of 923391 animals including 424167 sheep, 163070 goats, 264351 cow, 33133 buffalo and 38670 camel, inspected macroscopically for hydatidosis in 10-year period, out of which 9909, 2250, 6387, 740 and 414 respectively were infected with hydatidosis. The incidence of the disease in all slaughtered animals varied according to the province, but in general, Al Muthanna province recorded the highest incidence among all slaughtered species followed by Al Qadysiah then Al Najaf province. Buffalo recorded the highest incidence percentage (5.5%) in Al Muthanna and sheep (3.8%) in AlQadysiah while in AL Najaf cow showed the highest incidence (2.1%). The current results provide a baseline data for the prevalence of this parasitic disease in these three provinces and its incidence among different species of ruminants, which provide the opportunity for future monitoring and evaluation leading to control programs of hydatid cyst in Iraq.
