Contaminated meats are breeding ground for various bacteria. These bad meats cause food poisoning and are dangerous to your health! That’s why meats, poultry and fish should be handled and processed carefully to prevent spoilage. In today’s post, we are listing down common food-borne diseases from contaminated meats, fish or poultry:


This condition is caused by worm larvae that infest marine animals, including fish. Anisakiasis occurs when a person unknowingly ingests raw fish with worm eggs. The eggs then hatch within the body, causing serious health problems. Anisakiasis’ symptoms include odd itching sensation and coughing or vomiting live worms. This condition is treatable, but it will take a while to flush the body of worms. You can prevent anisakiasis by cooking fish thoroughly or blast freezing the fish at -31 Fahrenheit for fifteen hours. Finally, do not eat sushi unless it’s made from high-quality fish flesh.


This condition is caused by campylobacter, a curved bacteria that infests cats, dogs, and livestock. Campylobacteriosis is often caused by undercooked or raw chicken meat. The bacteria will go straight to the intestines where it will weaken the immune system and cause nerve inflammation. Symptoms of campylobacteriosis include watery stool or diarrhea, stomach cramps, nausea and fever. In severe cases, infection from campylobacter leads to Guillain-Barre syndrome. To prevent campylobacteriosis, prepare the chicken meats well. Wash your hands thoroughly if you come in contact with animals that carry this bacteria.

  1. coli
  2. coli is caused by undercooked beef. It’s also caused by exposure to feces of infected cows. Symptoms of E. coli infection include severe diarrhea, bloody diarrhea, vomiting, nausea and fever. It also causes stomach cramps. In severe infection, E. coli causes death by kidney failure. To prevent contamination, cook the meat extremely well. We recommend handling and storing the meat well to prevent contamination.


Although rare, listeriosis infection causes severe symptoms. This condition is caused by the listeria monocytogenes. Listeriosis typically originates from contaminated deli meat and hot dogs.

The infection affects newborn, women and the elderly. Symptoms of listeriosis include sore muscles, imbalance, confusion and fever. To prevent this infection, cook the meats well. In addition, comply with the standard pasteurization procedure to destroy listeria monocytogenes. Deep freezing processed meats won’t destroy the bacteria. They have to be destroyed by heat.


Apart from E. coli, salmonella is one of the most common causes of food poisoning. It’s caused by salmonellosis, a bacteria found in cat, dog, horses and livestock feces. It’s also caused by poorly prepared chicken meat. Symptoms of salmonella poisoning include fever, diarrhea and stomach cramps. Those infected with salmonellosis will require immediate medical attention especially if the infection spreads to the organs.


Toxoplasmosis is a parasitic disease caused by protozoan Toxoplasma gondii. This condition is typically caused by improperly handled lamb, venison and pork. The meat becomes contaminated from water teeming with the toxoplasmosis parasite.

The symptoms of toxoplasmosis includes achy muscles, flu-like symptoms, fever and swollen glands. Unfortunately, pregnant women afflicted with this condition could pass toxoplasmosis to their unborn child. And if that happens, it will lead to poor fetal growth, premature delivery or even fetus death.
