Chemical Food Contaminant in detail

Chemical Food Contaminant

Pesticide Residue

  • Meals grown organically have less residues than foods grown traditionally.
  • According to organic certification programs, land must be devoid of chemical inputs for two or three years before organic cultivation may begin.
  • Due to historical land uses and chemical drifts from conventionally managed farms, there may be low quantities of pesticides present.
  • It must be below the permitted maximum residue levels.
  • Biological control is the recommended approach to managing pests in organic farming.

Nitrates From Fertilizers

  • Crops grown organically are said to have much less nitrates than those grown conventionally, especially nitrophilic leaf, root, and tuber crops.
    • Methaemoglobinaema (a disease that interferes with oxygen carrying capacity of blood).
    • Nitrosomine illness is caused by presence of secondary amines, which causes cancer in human beings.
    • Feroxyl nitrates, alkyl nitrates, vapours of HNO3 and nitrate aerosols causes respiratory illness.
    • Entrophication
    • Under certain conditions, nitrates may be converted to nitrosamines which are carcinogenic.

Environmental Contaminants

  • due to mining and smelting operations, the energy industry, agricultural practises, or the discharge of municipal and hazardous wastes.
  • The usage of biosolids (sludge) causes food to become contaminated with harmful organic chemicals (such dioxin and PCB) as well as persistent microbial infections.
  • Sewage sludge use is prohibited under the EU and Codex organic standards.

Veterinary Drugs and Contaminants in Animal Feeds

  • The potential for contamination with pesticide residues and other agricultural chemicals is significantly reduced compared to conventional farming methods when livestock are fed organically produced feed, as required by EC regulations.
  • Animal feed contaminants like radioactive nuclides, heavy metals, agricultural and industrial chemicals, and pesticide residues could cause issues.
  • In Denmark, organic milk currently account for 20 per cent of total milk production.
