Pathogens contamination

The important quality criterion is absence of pathogens, a term which covers all disease-bearing bacteria. This criterion is usually determined by test for Eschericia coli, a species of bacteria so common in the gut that it is a reliable indicator of any pathogenic contamination. 

Finally, Part III also includes two reviews (Chapters 17 and 19) of the relative risks and novel strategies available to reduce mycotoxin and enteric pathogen contamination in organic crop production systems, for mycotoxin and fungal alkaloid contamination in organic and conventional production systems (Chapter 17) and for the microbiological safety of fruit and vegetables (Chapter 19). 

Pathogen contamination can occur at every stage of the whole production chain from field-to-fork (Table 19.1). Nevertheless, besides other components of infection, manures derived from livestock are considered to be an important potential preharvest contamination source (Fig. 19.1). Several disease outbreaks have been associated with raw fruits and vegetables and unpasteurised products some have been traced back to livestock (Pell, 1997), but in the majority of the outbreaks associated with fresh produce, minimally processed products and unpasteurised products, the source of contamination remains unknown (de Roever, 1998).

Sodium azide may react with lead and copper plumbing to form highly explosive metal azides. If allowed in your region, flush with a large volume of water to prevent azide accumulation. Because of possible pathogenic contamination, use of human blood serum is not recommended. 

With Mayor Vineyard in office, you went to a clean beach this past summer. My team got rid of the floatable problem, she boasts. You and your families were able to eat that lobster without worrying about pathogen contamination and to go clamming Sunday morning. I am the candidate who cares about the future of this island environmentally, and I proved it with the reopening of Beach A after ten years of contamination problems and Beach B after fifteen years. ... 

Linda is an environmental engineer who works for the island s Department of Environmental Protection on the pathogen contamination project, which she has led for the past 10 years. She is not really sure who to vote for, but she knows that Mayor Vineyard s boasts are not the whole truth. Two weeks before election time she is contacted by Mayor Vineyard s public relations director.
