| I have been curious as to how e coli has become systemic in plants. Is it just in certain plants? In the leaves, or all the way into the fruit?
If any one has any insight to this I would appreciate hearing about it. Thank you in advance. .rick. |

Quote: Could you please elaborate on "systemic in plants"? The only situations I have heard about is contamination of surfaces. Some surfaces are reported to be difficult to wash sufficiently to decontaminate. I have read that some spinach surfaces may be especially difficult to wash but the source of this is popular media and subject to the usual doubts. |

| Thank you Albert, "systemic in plants", from my understanding is that the bacteria is actually taken into the plants and survives inside of the living tissue becoming a part of the system. I first heard it on the news in January or so of this year. Then a series of articles on food safety in a fruit growers magazine, said the same thing. Neither one did any follow up or provided an indication as to how this happens. |

| Hi, There are some articles about this to be found using Google. I read that infection with other plant pathogens enhances the ability of E.coli to enter the internal tissues of the plant and multiply- this going hand in hand with the production of glucose that sometimes accompanies injury. Also, it is believed that plant pathogens, which may harbour antibiotic-resistant genes can transfer these genes to E.coli in plant tissues. I had not heard of this before- it goes to show how important it is for not only consumers, but also the growers to maintain sanitary conditions for the crops!

| Thank you Gemuse, That is exactly the type of info I have been looking for since I heard the news that day. You are obviously better at Google than I. If I read this correctly the E coli enters the plant as a decaying mechanism on the surface of dead tissue, rather than a disease in a living organism. I was under the impression that e coli was circulating throughout the plant, surviving on who knows what. I found it interesting though that the research team believe it may survive to another generation through seed. much appreciated, .rick. |

| I don't think it could circulate through the plant, aren't seive plates supposed to filter them out? |
