The present study examined the interrelationships of roasting methods and nitrosamine compounds (NA) content in eleven food sample investigated. The total level of NA in examined food ranged from 1.1x10-3 μg per g in oven roasted white maize to 5.0x10-3 μg per g in wood roasted pig meat that is lower than the legal level in WHO (0.001 μg per kg ). The significant increase of NA concentration in all food samples on roasting was observed. Methods of roasting have significant effects on the level of nitrosamine in each of the material used.

The field study involved 4 sites and 15 samples according to the wind directions: North, East, South and West. The analysis was conducted through the use of Atomic Absorption spectroscopy (AAS). Ten types of heavy metals were identified as indicators for pollution namely Mg, Ca, Mn, Fe, Cu, Zn, Pb, Ni, Cr, and Cd. The results indicated that the concentration of Fe was the most dominant per specific distances and depths and exceeded the minimum standard in North, East and West directions. While Cu was the second most dominant with concentration exceeding minimum standard per specific distance and depth, mainly in the West direction. The results have shown presence of bacterial species including Pseudomonas, Mirococcus, Actinomyces, Neisseria, Bacillus and Klebsiella. These pathogens can infect wounds and cause sepsis and mortality and can even occur with such organisms to cause secondary infection. These groups of organisms are almost impossible to control since they are ubitiquous.

Poultry production as one of the major sources of protein in Nigeria is constrained by parasitic diseases including haemo- and gastrointestinal (GI) parasites. The haemo- and endoparasites of indigenous chickens reared in Gwagwalada market, Gwagwalada Area Council, Abuja, Nigeria were studied. Blood and fecal samples were collected from 108 chickens (Gallus gallus domesticus) between April–August, 2017. Thin blood smear, and floatation and sedimentation techniques were used for the blood and fecal samples, respectively. Of the 108 local chickens examined, 49 were males, while 59 were females. Overall, female chickens had higher infection rate with haemoparasites (53.1%) that males (46.9%). The blood parasites found mostly were Plasmodium spp., with a prevalence 54.6%, occurring in both male and female chickens examined. It was further revealed that endoparasites infected 60.8% of the female local chicken and 39.2% of the male. The mostly occured Ascaridia spp. with prevalence 35.2%; the least was Strongyloides avium (0.9%). Also, Eimeria spp. occysts were found in 8 (7.4%) of the chickens. This study provides basic information on the haemo- and endoparasites constantly infecting local breed of chickens reared in Gwagwalada Area Council, FCT- Abuja
