“…Chicken meat, beef, and fish are important sources of zinc. Consumption of an increased amount of zinc may result in reduced Ca absorption further causing anemia while consumption of a very high amount was unsafe and may cause prostate cancer (Oloruntoba & Nathaniel, 2019 ). The safe limit for Zn is 0.41–5 ppm (Joyce et al, 2016 ).…”

The current study was designed to assess the safety and quality status of street‐vended barbecue chicken samples. The samples were collected from four regions of Faisalabad city: Ghulam Mohammad Abad (R 1 ), Jhang Road (R 2 ), Sargodha Road (R 3 ), and Satiana Road (R 4 ); and compared with the self‐prepared barbecue chicken sample (R 0 ). Purposely, all the collected samples were subjected to assess the quality aspects by physicochemical analyses. The results of the physicochemical analysis showed that moisture content varied from 54% to 60%, crude protein 26.97% to 32.87%, crude fat 7.25% to 9.00%, crude ash 1.61% to 1.72%, pH 5.60 to 6.30, free fatty acid value 1.00% to 1.39%, and peroxide value 0.63 to 0.84 meq/Kg. Results pertaining to the enumeration of total microbial load and total coliform count exhibit 2.39–5.17 and 1.20–3.20 log cfu/g, respectively. The samples were assessed for heavy metals (Pb, Zn, Cd, and Fe) by atomic absorption spectrophotometer (AAS). The concentration of highly toxic metals Pb and Cd was found to be much higher than recommended value as they ranged from 1.90 to 3.70 mg/kg for Pb and 0.10 to 0.90 mg/kg for Cd. However, the level of essential metals (Fe and Zn) in barbecue chicken samples ranged from 67.10 to 180 and 8.30 to 35.80 mg/kg which was much higher than their safe limits for Fe (15 ppm) and Zn (5 ppm), respectively. The study concludes that the consumption of street‐vended barbecue chicken possesses to be a serious public health risk for consumers.

“…Animal by-products, also known as the “fifth quarter”, “offal meats”, “organ meats”, or “assortment meats” encompass the nonmeat portions of the carcass [ 8 , 29 , 45 , 46 , 47 , 48 ] intended for human consumption [ 49 , 50 , 51 , 52 ]. The use of animal by-products varies globally, influenced by customs, traditions, culture, and religion [ 14 , 53 ].…”

“…The European Union (EU) defines [ 55 ] “meat” as the edible parts of animals, including blood, whereas “offal” is categorized as fresh meat apart from the carcass, comprising viscera and blood, thus excluding skeletal muscle ( Figure 2 ). Offal encompasses smooth muscle and internal organs like the liver, kidneys, heart, tongue, pancreas, spleen, brain, intestines, lungs [ 13 , 19 , 20 , 23 , 29 , 30 , 36 , 39 , 45 , 56 , 57 , 58 , 59 , 60 ], and blood, all of which serve as food ingredients [ 4 , 55 ].…”

The global increase in demand for meat leads to substantial quantities of by-products, including edible offal from both wild and domesticated animals raised for diversified consumption products within an agricultural framework. Information on the nutritional value of offal is scattered and limited. This review aims to synthesize scientific publications on the potential of offal as a source of nutrients and bioactive substances in human diets. The literature review included publications available in ISI Web of Science and Google Scholar published between 2014 and 2024. Findings indicate that edible offal is characterized by a nutrient concentration often surpassing that found in skeletal muscle. This review discusses the yield of edible offal and explores factors influencing human consumption. Selected factors affecting the nutritional value of offal of various animals and the importance of individual nutrients in ensuring the proper functioning of the human body were analyzed. The optimal use of offal in processing and catering can significantly benefit aspects of human life, including diet quality, food security, and conservation of natural resources.

“…With this observation, there might be no fear of acute toxicity when rice is consumed since the concentration is below the WHO permissible limits of 3.0 mg/kg in food and soil [32]. However, in green pea vegetables sold in markets around Abuja vicinity,cadmium levels were seen to be high in concentration [33].…”

Aim: Assess the levels of heavy metals: arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) in three different sites of the major rice growing soils and determine its accumulation in the rice grown on the same site in Nnatu St Azuuiyi Udene, Abakiliki, Ebonyi State. Study Design: Soil and rice samples were collected from three different farm locations into properly labeled plastic bags respectively using a 9mm soil Augerin Nnatu St AzuuiyiUdene, Abakiliki, Ebonyi State. Methodology: The collected samples were air-dried, ground, sieved and acid digested. The heavy metals in the samples were measured by atomic absorption spectrophotometer PG instrument AA500 FPC model. Results: The Mean ± SD (mg/kg) of heavy metals in rice were; As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 0.3620. Cu: 0.001 in site 1 whereas in Site 2; As: 0.0013, Cd:0.001, Pb:0.002, Zn:0.5040, Cu:0. 001. In site 3, the metals in rice were; As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 0.1950, and Cu: 0.040 respectively. The levels in the soil samples in site 1 were; As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 1.932. Cu: 0. 0267. In site 2, As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 1.597, Cu: 0.1550 and in site 3. As: 0.0013, Cd: 0.001, Pb: 0.002, Zn: 3.383, Cu: 0.0730 respectively. The mean values for arsenic, cadmium and lead in the soil and rice samples, respectively, were not significantly different (P > 0.05) in the three different sites whereas, for copper and zinc, the mean values were significantly different (P < 0.05) from each other at the different spots with an elevated concentration of copper and zinc in the soil samples than in the rice samples. However, these values were far lower than the values indicated by the World Health Organization as hazardous. Conclusion: The rice samples grown in Nnatu St AzuuiyiUdene, Abakiliki is safe for consumption.
