The Correct Option is C
Solution and Explanation
To determine which organism releases histamine and causes scombroid fish poisoning, we need to understand the context of scombroid poisoning. It occurs when certain types of fish, such as tuna and mackerel, containing high levels of histidine, are improperly stored at warm temperatures. Bacteria convert histidine to histamine, leading to poisoning when consumed.
Among the given options:
| Organism | Relation to Histamine |
|---|---|
| Salmonella | No known role in histamine production related to scombroid poisoning. |
| Staphylococcus | Known for producing toxins, but not specifically linked to histamine in this context. |
| P. aeruginosa | Can produce enzymes that convert histidine to histamine, leading to scombroid poisoning. |
| Weissella | Not associated with histamine production in scombroid poisoning. |
Based on this information, P. aeruginosa is known for producing the necessary enzymes that convert histidine to histamine, which can result in scombroid fish poisoning. Therefore, P. aeruginosa is the correct answer.
