The Centers for Disease Control and Prevention (CDC), USA, is warning people aged 50 years or more to reheat their cold meat before eating, to avoid listeriosis – listeria infection. For those over 50, and especially over 65, such meats as hot-dogs, cold cuts, luncheon and deli meats should be heated to at least 165 degrees, what the CDC describes as “steaming hot”.

The CDC adds that any opened package of sliced meat should be thrown out within five days.

Listeria is much less common than salmonella or E. coli. However, it can be extremely deadly.

As Spring advances and the days get warmer, there are more group gatherings and a higher consumption of processed meats.

The problem with listeria is that it does not hold back in cold temperatures – put the cold meat in the fridge and it will continue to reproduce. The CDC says the concern over listeriosis in the USA is not new; it seems people are just not paying attention.

    Eating uncoocked meat, fish or cheese can be very safe if these products are protected by Listex P 100.

    Listex P100 a phage preparation, is produced by EBI Foodsafety in Wageningen Netherlands. ( )

    Listex is approved by FDA (GRAS = generally recognised as safe). It is a very safe product. It is cheap, it does not change properties of the product – odor,color, taste etc. It only attacs Listeria and not the many good bacteria like those in cheese. Ik is a cheap product. If foodproducers do not use it they are playing with lives.

    I recommend to watch the above mentioned site. This tells you every thing you (and producers of food) need to know about avoiding Listeria monocytogenes..

    Not long ago I sent you a letter about control of Listeria monocytogenes with Listex. As a former listeriosos patient I know how terrible this disease can be, do you realize you suffer for years? Though I am happy I survived, I want to help avoid unnecessary suffering. Now I heard the USDA has okayed LISTEX as Processing Aid against Listeria. You can read about this in the news if you Google it, i.e.
    The website of the company which produces Listex is
    If possible I would like to know how food producers could be forced to ban Listeria. Please drop me a line on my e-mail
