The US Food and Drug Administration has identified red onions grown by California-based Thomson International, as a potential source of acute intestinal infection.
In conjunction with the US warnings, the Canadian authorities announced that more than 100 cases of Salmonella had been detected.
Usually these bacteria come from meat, poultry, or raw eggs, but they may reach the human being through fruits and vegetables, if they are irrigated or washed with contaminated water.
Although it is not a fatal infection, its effect can reach all parts of the body if it enters the bloodstream, as the digestive system does not return to its normal state until months later.
Symptoms of this disease include fever, diarrhea, and digestive disorders. Symptoms can also be accompanied by severe dehydration in the body, which calls for urgent medical care.
And medical authorities in the United States recommend anyone suspected of having an onion product from this resource, to the necessity of sterilizing surfaces or storage areas and cutting boards, which can cause the transmission of these bacteria.
Salmonella is a bacterial infection that affects the digestive system and lives inside the intestine, and reaches the body if a person consumes or drinks contaminated food.
