There are a variety of ways that the bacteria can spread to produce such as fruits:
- Contaminated water may be sprayed onto the fruit.
- Fruits that grow close to the ground may come in contact with infected manure used as fertilizer.
- Failure to sterilize surfaces and utensils can spread the bacteria from other foods to the fruit.

Previous reports showed that Salmonella persist in soil for at least 21 days when originating from pig manure (Pornsukarom and Thakur, 2016) and up to one year when originating from poultry manure (Hruby et al., 2018), indicating that soils can act as a long-term Salmonella reservoir.
How did salmonella get into onions?
Generally, salmonella outbreaks are linked to contamination from post-harvest handling when products come into contact with the bacteria during cutting, washing, packing and preparation processes. But with this outbreak linked to whole raw onions, the contamination likely occurred pre-harvest.
Can salmonella transfer to plants?
Wild type Salmonella are able to attach to plant surfaces and infect plants via stomata openings or roots. Upon infection, Salmonella hinder the enhanced production of reactive oxygen species (ROS) and prevent pH changes in the apoplast.
Can salmonella live in soil?
Salmonella can persist in water, soil, and on surfaces, and can survive for at least a year in soil [16], from weeks to months in water and on plants [17], and up to a month in infected pig waste slurry after it is spread into the environment [18].
What is microbial intoxication?
Microbial intoxication is caused by ingestion of foods containing the toxins or waste products produced by microbes. These toxins are difficult to destroy. The organisms may be destroyed but the toxins are not. Staphyloccocus Aereus and Clostridium Perfringens are examples, among others. The incubation period is fairly rapid. Staphyloccocus illness can present in a few minutes.
How do you get an infection?
The second means of infection is by inhalation of bacteria or viruses. Some disease-causing pathogens are carried in the droplets of saliva that are aerosolized (made into very small droplets) by coughing or sneezing. Someone breathes in the pathogens, and if the pathogen finds an environment suitable for growth, such as lots of mucus in a warm and moist place, like the lungs or the sinuses or the nasal passages or throat, then it may be able to attach itself to the body’s cells and reproduce, causing illness. People with more robust immune response may be able to resist such infections, accounting for those annoying people we all know who never catch a cold or other illness. To prevent such injuries, one should wear a mask in the presence of sick persons or avoid close contact with such people. It is believed by some that taking vitamin C supplements or zinc supplements can boost one’s immune system and prevent such infections.
What are prions in animals?
Prions are very small pathogens that are present in certain animal tissues and can be the cause of infection in humans by ingestion of that animal tissue. For example, mad cow disease and deer chronic wasting disease are caused by prions in the brains of cows or deer and can be contracted by eating those brains or other animal products that have come into contact with those brains. Some animal brains are used as feed for other animals, and that is how it is believed such diseases have spread in the past.
Why is it important to know the pathogens?
Knowing the pathways that pathogens can take into our bodies can help us to understand how to prevent infection with those pathogens.
How to prevent salmonella in cast iron?
The only ways to prevent such infections (if you don’t have a cast iron stomach) is to keep food cold until cooking it, and then heat it high enough to kill the salmonella, and to keep surfaces clean, and to take care to prevent cross contamination of one food with the juices of another.
What foods can cause salmonella?
Salmonella outbreaks are commonly associated with eggs, meat and poultry, but these bacteria can also contaminate other foods such as fruits and vegetables.Foods that are most likely to contain Salmonella include raw or undercooked eggs, raw milk, contaminated water, and raw or undercooked meats.
What is the third way of infection?
The third means of infection is through the GI tract. This is the most common cause of infection. Some pathogens, such as salmonella, can be on the surface of foods and then be introduced into the body by eating those foods. Salmonella produces a human toxin as it reproduces. (It’s not toxic to the bacterium, or to certain other animals like dogs and scavengers.) So, if the food with salmonella contamination is prepared in a way that allows the toxin to form, the people eating that food will get sick.

How long does it take for the mitogen-activated protein kinases 3 and 6 to activate?
Although regulating proteins such as the two mitogen-activated protein kinases 3 and 6 are activated just 15 minutes after Salmonella has infected the plant, they cannot prevent the bacteria from multiplying. Another defence mechanism, which is activated by the plant messengers salicylic acid, jasmonic acid and ethylene, proves similarly ineffective. Although these messengers are important to coregraph the plant defense responses, they too are unable to halt the infection."
