DOST scientist warns against increasing foodborne illness cases in the Philippines
A Balik scientist and inventor of the Department of Science and Technology (DOST), Dr. Homer Pantua, raised concerns about the increasing cases of Salmonella in the Philippines — a bacteria affecting both humans and animals.

In an interview on PTV on Monday, March 4, he defined Salmonella as a "zoonotic disease" affecting a decrease in productivity for animals, while in humans it manifests as foodborne salmonellosis that can lead to gastrointestinal issues, fever, and abdominal cramps.
The global statistics revealed that there are already 83 million cases, and in the Philippines, he cited that there is a 42 percent increase from 2022 to 2023, from January to August — jumping from 9,000 to 13,000 reported cases.
When asked, aside from eggs or raw foods, what are the others that can come from salmonella, he said that it can come from our food chain, like eggs and meat, especially when it is not processed properly.
“Usually, these are the foods that are exposed, or what we call contaminated,” he added, as contamination may occur throughout the food chain, from animal rearing to processing and preparation.
Pantua also clarified the difference between Salmonella and E. coli, another bacteria that can cause foodborne illnesses.
He emphasized that while both can share some common sources, Salmonella is primarily transmitted through food, whereas E. coli can also develop from environmental sources.
“So diagnostics is very important," he said. “It is very important that we determine what is the cause of this disease in humans and animals,” he added.
The expert also mentioned the ongoing efforts with egg producers and research institutions to ensure the safety and quality of the food chain.
“So that is what we're doing now, as scientists, We're talking to producers and then to research institutions like the University of the Philippines Diliman (UPD), what we call the Institute of Biological Sciences,” he said.
“Now we are with BEPCO, the Batangas Egg Producers Cooperative, we determine if the eggs are contaminated with salmonella," he added.
