These hazards include: fires and explosions from grain dust accumulation, suffocation from engulfment and entrapment in grain bins, falls from heights and crushing injuries and amputations from grain handling equipment. Suffocation is a leading cause of death in grain storage bins.
We found that grains represent a significant source of foodborne contaminants, the main ones being; mycotoxins including (A) aflatoxin B1; (B) ochratoxin A; (C) fumonisin B1; (D) deoxynivalenol; (E) zearalenone; toxic metals like arsenic, cadmium and lead; as well as process contaminants such as acrylamide.
GRAIN PRODUCTION IN INDIA Indian food grains production is increasing steadily: Advancement in cultivation technologies Development of new grain verities Use of fertilizers Annually India produces more than 250 million tonnes of all major food grains India is second largest producer of wheat (97 million tonnes) and rice (111 million tonnes) in the world
Grain cleaning is the most effective nondestructive postharvest mitigation strategy to reduce high levels of mycotoxins on account of the removal of moldinfected grains and grain fractions with high mycotoxin content. In this study, the reduction in the concentration of some cooccurring Fusarium toxins in maize, namely deoxynivalenol (DON), zearalenone (ZEA) and fumonisins B1 and B2 (FBs ...
GMP HACCP TACCP CARVER + Shock Introduction At a basic level, foodsafety management requires: identification of the hazard; factors (risk factors) which influence the frequency and degree to which the hazard occurs and; the processes necessary to reduce the risk of the hazard occurring.
Drymilling of maize (with hull, bran meal, germ, and fines as disposable fractions) (Brekke et al., 1975; Brera et al., 2006; Pietri et al., 2009) ... They also present one of food safety pillars needed for quantitative measurement of health risks associated with mycotoxins. Proposed prevention and intervention strategies can also be applied ...
The maize stalk or stem borer is a widespread pest, found throughout tropical and subtropical areas of Africa, and is one of the major pests of maize. Busseola fusca larvae damage all plant parts of the crops they attack. If farmers do not use controls then infestations can cause yield losses as high as 50%.
Electricity Needless to say, loadshedding results in a lot of wastage, from the mill stopping and starting, to product changes that mean the maize meal has to be discarded, etc. When the miller stops the process, he stops the input streams and as a result, the output stream quality starts changing.
Introduction. Maize is an important staple food and one of the most consumed cereals worldwide (OECD/FAO, 2019). Like other cereals, however, maize is also a target of toxigenic fungal infections than can occur during the growing season or postharvest during storage and transportation, and which frequently causes contamination with mycotoxins (Eskola et al., 2020).
63. Dust explosions in the grain and milling industries usually start inside process equipment such as mills, dryers, mixers, classifiers, conveyors, and storage silos and hoppers. Dust explosions can cause catastrophic loss of life, injuries and destruction of facilities and assets. There have been many serious incidents dating back to 1878 ...
Maize stem (or stalk) borer. The Maize stem borer (Busseola fusca, Chilo partellus, Chilo orichalcociliellus, Sesamia calamistis) is still one of the most important pests that infect maize. It can cause significant damages (up to 5075% yield loss) in plantations of maize in developing countries (affects 30 million hectares(2)) but also in, Sorghum and sugarcane are other host ...
2. Subsistence Maize Farming and Agricultural Practices in South Africa. Foodstuffs such as sorghum, millet, cassava and peanuts are important staples and sources of revenue in the rural subsistence regions of southern Africa, but are prone to mycotoxin contamination [39,40,41,42,43,44].These crops are produced for direct consumption, for trading at informal markets and in some cases ...

This OSHA Technical Manual (OTM) chapter was prepared to educate readers about some of the safety and health hazards associated with the current and anticipated future production technologies for ethanol manufacturing facilities in the United States. Information in this OTM chapter is organized as follows:
the indigenes is dry milling and majority of the meals consumed in this area are products of milled maize and millet. This research there fore sought to unravel the levels of Fe, Mn, Ni, Pb, Cr, and Zn present in milled grains of maize and millet and further assess the associated potential health risks posed to their consumers.
All handheld grinding machines shall be complete with handle or commonly known as the 'T' bar. Removal of the handle during use is strictly prohibited. Each grinding machine shall be fitted with its correct guard as supplied by the manufacturer. The guard shall cover a minimum of 70% of the circumference of the rotating disc.
Never tamper with or make any adjustments to manufacturers guards or safety devices. Report all defects of Milling Machine Safety tools to your supervisor immediately once they are discovered. Never carry cut any cleaning maintenance work while the machine is in motion. Disconnect or isolate (lockout/ tag out) the power source to ensure the ...
Similarly, to wheat, maize milling methods produce a variety of economically and nutritionally valuable coproducts, which can be used as food ingredient (Naves et al., 2009). This study aimed at improving the nutritional profile of wheat bread using raw and heattreated wastes of maize milling process fermented by selected LAB.
Hold milling cutters with a cloth or wear gloves when handling them. Stay at the machine when it is in operation. Use the milling machine spindle brake to stop the spindle after the power has been turned off. Use the correct cutting fluids for the material being machined. Do not measure the workpiece while the milling machine spindle is rotating.
This code of practice is intended to raise awareness of the hazards and risks associated with agriculture and promote their effective management and control; to help prevent occupational accidents and diseases and improve the working environment in practice;
The effectiveness of most locally built metal silos (m. silo) has been tested in many studies, and the experienced maize grain weight loss was minimal and relatively close to that of m. silo + acc. Negligible, %, %, and less than 7% maize grain weight losses have been associated with using m. silo to store grain for at least 6 months.
handling tasks associated with changing heavy vices and indexing heads etc that can be beyond the physical ability of some people. Measures must be implemented to minimise the risks associated with lifting heavy items by the use of lifting aids, team lifts and correct lifting techniques. Adjustment and Setting Up of Machine
The Hazard Quotient (HQ) values as presented on Table 5 were all less than 1. Health risk analysis indicated the unlikelihood of any potential health hazard. The risk here might result from potential bioaccumulation [44]. Similar results were obtained for milled maize and millet in the Tolon district in Northern Ghana [43].
generic form, and do not know the associated hazards, contact the CGC for advice. Identify potential biological, chemical or physical hazards associated with each. Answer each question and fill in "B" for biological, "C" for chemical or "P" for physical hazard and identify the specific hazard, if a hazard exists.
Another simple ergonomic solution was demonstrated which reduced risks of MSDs associated with manual handling. The earlier method practiced by the workers was fill to the basket with turmeric, lift a load of about 1012 kg, and carry the basket to the turmeric mill located at a distance of 15 m (see Fig. 5a, b). The weight of each basket is ...
