Most housewives in the developing countries, grind their soup ingredients in public grinding micro-industry. Such method leaves room for reduced hygiene because the machines are not cleaned regularly as required by safety guidelines. More scaring is the effect of iron filings on the consumers of such soup. Persistent use of the grinding machine and installment release of iron filings into the ground ingredients is a source of scare. Consumption of these materials at levels not easily noticeable might lead to their accumulation in the various body organs leading to morbidities and possible eventual death. The metal used for the grinding disc is not the refined type and so it easily wears out and released residues as filings. Iron filings have also been reported in tea to a litigation level Pepper, tomatoes have implicated as possible carriers of these byproducts of grinding. At some point, it could become a subject of litigation as recorded on tea.
