Consumers’ interest in organic products is increasing globally. As IFOAM 2016 report, only 1.2 % of the land has been utilized in organic agriculture method. The overall organic market has achieved 89.7 billion $ in 2016 in that, & 48.4 a billion in sales accounted for the USA and German alone. Total registered organic producer in the worldwide is 2.7 million in that India is the leading country which has 835,200 organic producers. But many of them are a small farmer, and they had shared 1.49 million hectares only. The Government of India (GOI) and the state governments have taken several steps to improve the regulatory mechanism and frame several schemes to incentivize organic farming. 2017 December, Food Standards and Safety Authority of India (FSSAI) have recognized both the certification systems (NPOP and PGS-India) valid for organic food products. From these steps, GOI has tried to create confidence in the organic products, so that, domestic consumers and export countries can trust Indian organic products. But still, the organic sector in India suffered from some unique characteristic that is the absence of proper branding, package, consumer awareness, purchasing power, and supply chain issues (Agarwal, 2018).

Isolates (50) of E. coli obtained from liquid manure (20 bovine, 20 porcine) were genotyped using random amplified polymorphic DNA (RAPD). Typing revealed 9 and 14 different strains in bovine and porcine liquid manure respectively with no strains in common. One porcine strain, showing a simple RAPD pattern, was subcultured and spread on a test field (1.5l/m2 at 1010 cfu/l) in a drinking water protection zone with loamy to sandy sediments in the Donauried area, Baden-Wurttemberg. Soil samples and groundwaters were collected at monthly intervals October 1994 – June 1995 during which 114 E. coli isolates were recovered. The first occurrence and maximum concentration of E. coli in soil samples taken from more than 20cm depth was in January 1995, declining rapidly with depth and time. All isolates from soil and only one from groundwater showed the RAPD pattern of the spread E. coli strain. The results could not demonstrate a severe negative impact of the spreading of liquid manure on the bacteriological quality of the groundwater in the given geological situation. The distinct strain patterns found in different kinds of liquid manure suggest that genotyping of E. coli by RAPD may be an adequate tool for tracing sources of faecal contamination.
