According to the World Health Organization (WHO), there are two million reported cases of food poisoning in Nigeria with estimated deaths of 200000 people from food poisoning and 20000 deaths from exposure to food pesticides annually: children inclusive. These hotels make provision of letting rooms food and refreshment services in restaurant bars and banqueting rooms, conference/mailing rooms, and leisure facilities it was expressed that, threats identified with the production of food items can be minimized to a permissible limit or eliminated through the utilization of HACCP procedure. This study assessed the knowledge of HACCP of food handlers in standard hotels in Lagos State. The study adopted a cross-sectional survey research design and was conducted in Lagos. All the hotels classified by the Nigeria Tourism Development Corporation as either three, four, or five-star-rated were targeted. A purposive and stratified sampling technique was used to select the study units who constituted the respondents for the study with a total of 31 hotels involved in the study. A questionnaire was used to get information on knowledge on HACCP and its implementation by 31 food handlers. Data were presented in tables. Findings from this study have revealed that under 20% of the respondents in the various hotels use HACCP as a quality control strategy, less than 50% understand the concept of HACCP. Results also revealed that there is an insignificant relationship between years of service in the food establishment and the knowledge on HACCP at P value (0.05). More results revealed that there is no significant relationship between formal training and knowledge on food safety. Results also revealed that there is no significant relationship between knowledge of HACCP by food handlers and their implementation in food preparation with a P-value at (0.05). This insignificant relationship between formal training and knowledge on food safety could mean that there may be other factors preventing food handlers from implementing food safety practices, this may include time, cost of carrying out the practices, or even personal attitude of the food handlers during food handling. Food handlers should be taught food safety practices practically rather than theoretically.

Microplastic pollution is now globally flagged as a foremost menace to livelihoods, biodiversity, and public health due the pervasive nature of plastic wastes, poor knowledge of its ecological impact and poor attitude towards sustainable waste management practices. Hence, this paper explores public awareness, knowledge, attitude and perception on Microplastic pollution and its ecological health implication through a survey data collected from residents, students, fishermen and local tourist around Lagos Lagoon, a significant area in Lagos. Findings revealed that though awareness on microplastics was apparently high (over 50%), however, public knowledge was fairly acceptable and poor perception on Microplastic pollution was observed. Respondents (with a mean attitude score of 3.40±1.485) generally shows a good attitude towards learning more on this subject and a shared commitment to support government through cleanup volunteering and advocacy. In light of this findings, this study recommends that government, academia and relevant stakeholders should intensify efforts to educate the public more on issues of public health importance through massive campaigns, learned community activities and strategies that may reinforce positive environmental attitude.

“…Land-based activities account for approximately 80% of marine pollution. Plastics, fertilizers, and organic compounds are contaminants of concern in marine ecosystems due to the erosive effects of polluted water and soils (Hussain et al, 2021a;Hussain et al, 2021b;Isah et al, 2020a;Isah et al, 2020b;Morufu et al, 2021b;Olalekan et al, 2020b;Koleayo et al, 2021;Olalekan et al, 2021).…”

BackgroundOil and natural gas extraction have produced environmental pollution at levels that affect reproductive health of indigenous populations. Accordingly, polluted drinking water from physical, chemical and heavy metals can result in serious health problems, like anemia, kidney failure, immunosuppression, neurological impairments, gastrointestinal as well as respiratory irritation, skeletal system abnormalities, liver inflammation, liver cancer, cardiovascular diseases after chronic exposure and other cancer diseases with negative health effects. These diseases types remain associated to high amounts of heavy metal elements such as lead, chromium, zinc, copper, cadmium, manganese as well as nickel etc.ObjectivesCompare differences in water quality parameters in the study area (determine the level of pollutions in the different sites).MethodologyThe investigation made use of standard analytical procedures. All sampling, conservation, transportation and analysis followed standard procedures described in APHA (2012). To prevent degradation of the organic substances, all obtained samples were transferred to the laboratory, while keeping in an icebox.ResultsResult shows that during wet season, the mean values obtained for water quality parameters were significantly lower in site 9 compared with that obtained in other sites (p<0.05) with the exemptions of temperature, DO, BOD, COD, acidity, TH, TDS, K, Mg, Zn, Mn, Cd, Pb, Cu, Cr, NH3, NO2, NO3, Ni though slightly lower in most cases in site 9 were not significantly different (p>0.05) and both alkalinity and SO4 which were significantly higher in site 9 than site 1 (p<0.05). Result obtained during dry season reveals that there is no remarkable difference in pH, acidity, Pb and Ni between the nine sites (p>0.05) while other water quality parameters were significantly lower in site 9 than other sites excluding Cl and Mg which were both significantly higher in site 9 than site 8 (p<0.05).ConclusionTo guarantee quality groundwater supply for various purposes in Nigeria’s core Niger Delta region, extra efforts must be taken to fully understand hydrogeochemical features and its suitability. Thus, this study will aid in the development of a quantitative understanding of the effects of diverse causes on groundwater level fluctuations in any aquifer around the world. Also, this analysis reinforces a valuable resource for researchers, activists and public officials seeking to help enhance community awareness, planning and performance. The verdicts would remain a valuable guideline for policymakers, the Ministry of Water Resources and development practitioners, as this highlights the requirement for suitable approaches toward mitigating toxic element of water resources contamination in the core Niger Delta toward safeguarding health of the public from carcinogenic as well as non-carcinogenic risks.HIGHLIGHTSMany tropical countries are suffering from severe groundwater pollution. Governments at all levels are doing little or very little to provide clean and accessible water to citizens, especially in Nigeria’s Niger Delta region.This study aims to determine the level of pollutions in the different sites.Result depicts that during wet and dry season, the mean values obtained for water quality parameters were significantly lower in site 9 compared with that obtained in other sites.Result reveals that groundwater at location 3, 4 and 7 were heavily polluted during wet and dry season. Hence, an alliance is needed to address the rising global health emergency threat caused by groundwater pollution in Nigeria’s core Niger Delta region, which is threatening millions of people. The situation will only get worse and faster unless there is a coordinated response to the problem through a worldwide alliance of organizations capable of bringing meaningful change.The disease risk as well as illness to millions of individuals living in close proximity to gas flaring remain a cause for worry in its own right, the gases as well as toxins impact released into the atmosphere through continuously flaring gases has worldwide implications.Regarding the environmental and social conditions of the area, gas flaring significantly increases the health hazards, first through releasing dangerous pollutants directly into the atmosphere as well as through pollutants transfer to the food chain.Groundwater pollution has a financial cost that runs into billions of Naira, in addition to the human and environmental effect. Thus, there is need for tougher environmental regulations.At present, no coordinated action being taken, real change will only occur if governments as well as key stakeholder organizations form a global alliance toward addressing the issue. Starting with a strategy to finance well closure as well as relocation of sites that are most dangerous (location 3, 4 & 7) as soon as possible, as well as providing support through capital and experience is required. Even though the cost will remain substantial, it will provide an opportunity toward investing in the Niger Delta infrastructure as well as economy. Furthermore, the expense of closing the most dangerous groundwater open wells will be a drop in the bucket compared to the cost of the health consequences.
