In case you were wondering about that – here is your answer! Thanks to the Green Routine for some real good information.
…tomatoes can harbor Salmonella bacteria on their surface, and in rare cases within the tomato. So how does the bacteria end up in the tomato?
As it turns out, there are countless numbers of ways for Salmonella to spread on a farm. Most commonly Salmonella spreads into irrigation water supplies used for irrigation of crops from nearby livestock farms. The bacteria can also be spread by wild animals infected by the bacteria or by vegetables being processed on shared equipment. Contamination of crops is also common during flood conditions, such as those currently plaguing the mid-west
If you don’t want to block tomatoes out of your diet here are some tips on how to avoid eating a salmonella-infected tomato.
So what can I do?
There’s not much you can do to prevent Salmonella in tomatoes or other vegetables you may purchase at the grocery store. While I would love to recommend purchasing organic tomatoes, they are just as susceptible to Salmonella as non-organic vegetables. However, I do have a couple of suggestions.
Buy local if possible
If you have a local farmer’s market, get to know your local farmers. He or she may be able to assure you of his farms bio-security, which is a fancy term for ensuring that there aren’t any sick animals on or in the vicinity of the farm. Smaller farms may have more control of their product from end to end. Finally, there is the face to face factor – do you trust the farmer when he says “there is no Salmonella in his tomatoes?”
Always wash your tomatoes, cook them if you are suspicious
Washing tomatoes before you eat them is always a good practice. While Salmonella is not likely to wash off, a rinse with water might remove trace amounts of it or other toxins from the vegetable. In situations where there is an outbreak of Salmonella in tomatoes, and you are reasonably sure your tomatoes are not affected, but want to be absolutely sure – cook them thoroughly. I might suggest turning them into chili or spaghetti sauce. If your tomatoes meet the criteria of the tomatoes reported in the outbreak – throw them in the garbage (do not compost, or throw them down a drain).
Salmonella can affect any type of farm product including dairy, vegetables, and meats. Get to know your local farmers at farmer’s markets and buy local when possible. Buying local is good for the environment and the local economy. Always wash your vegetables before you cut into them. When in doubt, cook the vegetable. When your vegetable is suspect – throw it out!

Can Salmonella be caused by using dead fish as a fertilizer?

Hi Susan,
Sorry for the slow reply. I am not an expert on fertilizers or salmonella and I have been researching to find you an answer.
In general, I would think that any animal product can be a source for bacteria. They are carriers of bacteria and they would be the one’s that would infect the plant. But, FDA hasn’t confirmed anything about what is the main source for this issue.
So here is what I found when I did some research to find you an answer –
a) Link1- http://www.austin360.com/food_drink/content/food_drink/stories/2008/06/0618tomatoes.html
“Instead of manure compost, which is made from turkey, chicken or even bat guano and increases the risk for soil disease, Paquin uses fish oil, fish emulsion and seaweed for fertilizers, not to feed the plants but to feed what’s in the soil.”
b) Link2 – http://www.hyline.com/userdocs/library/Salmonella_Control.pdf
This one is about another strain of Salmonella, not the one infecting tomatoes. But here they talk about how you shouldn’t feed fish meal to the body that is a carrier for this bacteria.
c)Link3 – http://www.health.gov.au/internet/main/publishing.nsf/Content/cda-cdi3002e.htm
This research shows a lot of data – again for another strain of Salmonella. It seems like dead fish can also be a carrier for this strain of salmonella.
You should browse through the research and information provided in the links above. I couldn’t find anything else substantial enough to relate salmonella directly with dead fish fertilizer. But I’m keeping a track of the news to find out the source for the infection!
Please let me know if you have any more questions!

Thanks for the info.
Your suggestion to buy local really hit home.
In the past few years I have progressed from a typical supermarket shopper to one who prefers non-GMO, organic and locally sourced foods over the industrial food products offered up to the masses.
And it seems that this is becoming more mainstream. farmers Markets are popping up all over downtown Toronto, with farmers from just outside the city.
As well, Canada’s largest grocery chain is making a push towards local food

I have never tried buying in a local farmers market, but I am going to give it a shot soon. They have become really popular – there seems to be at least one farmer’s market in the area every day!
By the way, that is some great information on the 100 mile diet! I agree – our ecological footprint is extremely huge. I was totally bummed out when I tried to find what my ecological footprint was.

Truth Hurts
These explainations are pure crock. Salmonella outbreaks on veggies on a widespread scale is a new thing. Sure, a rogue wild animal might be able to pass the bacteria to a couple of veggies but these farms to not have wild animals coming into the crops lest they eat them all up. That is why the big farms make sure they protect their investment by keeping the critters out. Most livestock areas are so far from veggie growers that irrigation run off is not plausible at all. As far as veggies being “processed on shared equipment” You cannot process veggies on equipment that is used in processing meat and dairy.
Your propaganda and demagoguery about Organic produce being just as likely to have salmonella as non-organic and then suggesting local farmers as an option is ridiculous. Organic produce is the most rigorously overseen and tested in the industry. Unlike conventional chemical farming, Organic farmers undergo a strict set of standards and accountability.
So drop the propaganda campaign and get real with the facts.

Hi there,
Thank you for that information. As I mentioned above, I am not an expert in this matter and I am sharing whatever information I learn about. I wouldn’t have noticed those problems with the article if you hadn’t pointed them out. So, thank you very much. =)
Good catch about the organic produce! What I make out of that section of the article is that the author means don’t buy them at grocery stores – that also sell organic produce – as they won’t always know the condition of the farm that grows these products but local farmers that sell at the farmers market can tell you about the farm condition. I might be wrong, but that is what I make of the author’s advice to buy local.
In any case, an update for the post readers – FDA lifted the warning for eating tomatoes. So you don’t need to worry about all how salmonella can infect a tomato. They still don’t know the cause for the Salmonella outbreak and they are now investigating other veggies like cilantro and jalapeno.

Tomatoes prevent infection from Salmonella?! « ResearcHub
[...] in Eureka! today that I thought was pretty ironic. The past few months have been all about the Salmonella-on-tomatoes outbreak – which was concluded to be a Salmonella-on-jalapeno outbreak few weeks ago. But [...]
