Food Safety vs Food Security

  • PT. Angler BioChemLab

Food Security: The WHO defines fourth of food security: food availability, food access, food use, the stability over time Food Safety: A measure of that food will not cause pain or free from hazards caused by both the public perception and scientific study when it is prepared, served and eaten

Food Safety “ “Overlapping Aspect”

Food Safety vs Food Security

Food Security Basic Human Need : Adequate and SAFE supply of food Global Realities

Increasing Demand For Global Food Production

Today, Food must be like this . . . ?

SLIDE 5

In a broad sense includes

  • Consider the impact to the ecology, environment, animal welfare
  • Not only the acute but also chronic effects (carcinogen, allergens, etc.)
  • Labeling and the consumer's right to choose: organic, GMO, halal, veggie,

allergen, etc.

Food Safety

Factors that trigger update of food safety regulation

  • outbreak of food-borne illness
  • Microbiological and chemical

(ex. E.coli 0104:H4, melamine)

  • potential of new chemical hazard
  • emerging residue or contaminant found

in food (ex. 4-MEI, dioxin, PAH, mycotoxins, etc.)

  • new registration of pesticide,

agricultural chemical, food additive, veterinary drug, etc.

  • scandal of misused, fraud, adulteration

in food production (ex. melamine, mislabelling, etc.)

How many analyte do you need to analyze in single run?

Chromatogram of 300 pesticides at concentration 5ppb each

Multiresidue method have to include as many substances as possible and must be accurate, precise, sensitive, fast, widely applicable, selective, easy and robust.

Phytotoxins

Phytotoxins which occur in at least 2000 plant species, of which a number of species are used as food in some areas

  • f the world. Cassava and sorghum are

especially important staple foods containing cyanogenic glycosides

  • ¡Cyanogenic glycosides
  • Pyrrolizidine alkaloids

In 6000 plant species, Senecio, Boraginaceae,..

  • Occur in feed ; transfer to milk relevant
  • Occur in food ; hone, rocket salad
  • Highly toxic, genotoxic carcinogenic

In September 2012, traces of dicyandiamide were found in milk produced by New Zealand company Fonterra. eaten by cow accumulation contaminant in milk

  • PT. Angler BioChemLab

DCD (Dicyandiamide)

It does this by blocking the enzyme that causes oxidation of ammonium to nitrate in soil and thereby slowing down the release of nitrate to waterbodies, and the production of nitrous oxide via the process of denitrification.

Emerging Contaminant

slide-35
SLIDE 35

Formed from action of HCl on residual glycerides Produced naturally in foods during food manufacturing, cooking, and other processing activities such as deep frying and roasting Much of the 3-MCPD found in foods is present as 3-MCPD fatty acid esters (3-MCPD esters) and 3-MCPD esters are found in a wide range of food Forms: dichloropropanols, chloropropanediols, chloro-propanediol mono- and di- fatty acid esters, and glycidyl fatty acid esters MCPD fatty acid esters reported at high levels in refined oils (Zelinkovä et al. 2006) 3-MCPD causes infertility in rats and suppression of the immune function Genotoxic in several in-vitro assays, not genotoxic/mutagenic in-vivo (mice & rats), induced tumours in kidney, testes, mammary glands (rats)
