What temperature must previously reheated foods and leftovers be heated to?
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.
Where is clostridium botulinum most likley to be found?
Clostridium botulinum is commonly found in soil and aquatic environments. It can also be present in improperly processed canned foods, particularly low-acid foods with anaerobic conditions that allow the bacteria to grow and produce deadly botulinum toxin.
Can you refreeze vacuum packed swordfish?
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.
Why is botulism associated with canned foods and not fresh foods?
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.
What type of toxin is ciguatera toxin?
It is a biomicrobial toxin.
Is THC a toxin?
No, it is not a toxin.
What is the role of bacteria in human life?
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.

Is jellyfish toxin a base or an acid?
toxin
Which is the toxin produced by aspergillus?
Alfa toxin.
What's the definition of Botulism?
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.
What is the significance of clostridium botulinum being anaerobic?
Clostridium botulinum being anaerobic means that it thrives in the absence of oxygen. This is significant because it helps the bacteria to survive and produce its toxin, botulinum toxin, in environments where oxygen levels are low, such as in canned foods or in wounds.
