salmonella
In the US, the Food and Drug Administration department recommends a minimum temperature of 135 º F (57 º C). The danger zone is 41º F - 135º F. Potentially hazardous foods exposed to this temperature range for a cumulative total of more than 4 hours are not safe to eat. Pasta and rice dishes should be cooled to below 41ºF as quickly as possible to prevent the growth of Bacillus cereus that can produce a toxin, especially in foods that are cooled slowly. Because this toxin is heat-resistant, it's not destroyed by reheating to any temperature.
Unless you have a precise temperature history of the thawed swordfish, refreezing it would not be recommended. The vacuum packaging could promote the growth of C. boutlinum along with the formation of the toxin if it got above 38 degrees F. Swordfish can also produce histamines when temperature-abused which could result in Scombroid poisoning.
The botulinum toxin is formed when the bacteria, Clostridium botulinum, grows under anaerobic conditions. Improperly processed canned foods provide the ideal conditions for this kind of food poisoning. Canning will kill off vegetative cells, but C. bot. also produces a protected cell - called a spore - that can survive standard heat treatment.Botulism toxin has been found in the middle of improperly processed sausages, in packages of fresh mushrooms (that is why you see the hole punched in the overwrap) and in sealed packages of shredded cabbage. A often-cited outbreak occurred when grilled onions were covered with oil and placed near the grill. The oil provided the anaerobic environment. The onions provided the spore form of the bacteria, which germinated in the warm environment and produced the toxin. C. Bot. is also the reason you don't give honey to babies. Their digestive system is not mature enough and does not have the acid levels of adults. The bacterial spores germinate, grow and produce the toxin, resulting in illness or even death.
A substance that kills cells is known as a toxin. There are toxins in the foods and beverages that are consumed everyday.
It is a biomicrobial toxin.
No, it is not a toxin.
1.some bacteria cause diseases to human.Example is Salmonella typh i(typhoid fever) .2.The toxins of many pathogenic bacteria that are transmitted in foods can cause food poisoning when ingested. These include a toxin produced by Staphylococcus aureus, which causes a rapid, severe, but limited gastrointestinal distress, or the toxin of Clostridium botulinum, which is often lethal. Production of botulism toxin can occur in canned nonacidic foods that have been incompletely cooked before sealing.3.

Botulism is nothing but which can be defined as food poison caused by bacterias which are all growing on improperly sterilized tinned meats and other preserved foods.
