Population control of golden apple snails (GAS, Pomacea canaliculata) is beneficial in rice farming; however, the associated control measures can be expensive and time-consuming. Currently, farmers use synthetic molluscicides such as niclosamide to control GAS infestation, but this has some drawbacks. For example, niclosamide has broad toxicity to non-target organisms and negatively affects the growth of rice seedlings. Plant extracts with potent bioactivity and low toxicity to non-target organisms are attractive alternatives to synthetic molluscicides. In this study, the bioactivity of the crude fruit extract of tagpo (Ardisia tomentosa) was assessed against GAS and tilapia (Oreochromis niloticus) fries. The potential …
Microbiological And Physicochemical Changes In Rabbit Meat During Ambient Storage, Marielle Gamboa, Dennis Marvin Santiago, April Shayne Sulabo, Mary Ann Torio
Microbiological And Physicochemical Changes In Rabbit Meat During Ambient Storage, Marielle Gamboa, Dennis Marvin Santiago, April Shayne Sulabo, Mary Ann Torio
The Philippine Agricultural Scientist
This study aimed to evaluate the changes in rabbit meat during storage at ambient temperature (30 ± 1ºC) for nine hours. The study focused on two rabbit muscle parts: the hind leg and the saddle, investigated in terms of microbiological parameters such as aerobic plate count (APC) and total coliform count (TCC); and physicochemical parameters such as pH, color, total myoglobin concentration, and lipid oxidation. Data obtained were subjected to statistical analysis at a 5% significance level (p < 0.05). Results revealed that the pH of both portions of rabbit muscle decreases over time during storage. This decrease is attributed to the growth of acid-producing microorganisms, which ultimately leads to spoilage in rabbit meat. On the contrary, color values (L*, a*, and b*) showed an increasing trend in both muscle portions, indicating a discoloration of rabbit meat during storage. Both lipid oxidation and total myoglobin content of rabbit meat did not change significantly during storage, but lipid oxidation varied between muscle parts. Based on the microbiological analysis of rabbit meat, both aerobic plate count (APC) and total coliform count (TCC) increased significantly during storage in both muscle portions. Results of the study suggest that freshly slaughtered rabbit meat must remain at ambient storage for the shortest time, as this storage condition will cause spoilage of meat, making it unfit for human consumption.

This study evaluated the safety of Bignay (Antidesma bunius (L.) Spreng cv. ‘Kalabaw’) fruits through a sub-acute oral toxicity test in male and female ICR mice. The evaluation was done through oral gavage of the aqueous fruit sample at 2,000 mg kg-1 body weight dose for 28 d. Results showed that there were no significant changes in feed and water intake of male and female ICR mice as compared to the control groups that received distilled water (p < 0.05). Blood chemistry and hematology values for all mice groups were comparable to the controls and published values. All mice groups also had appreciable body weight gain (10.89% – 21.69%) with zero morbidity and mortality. Lastly, the gross and microscopic examination of the brain, heart, lungs, GI tract, liver, spleen, and kidneys showed normal architecture and histology, suggesting that the fruits did not induce any morphological abnormalities. Results of this study showed that Bignay (cv. ‘Kalabaw’) fruits are safe for consumption with an LD50 of greater than 2,000 mg kg-1 body weight.

Evaluation Of The Inactivation Kinetics Of Cronobacter Sakazakii In Infant Formula Treated By Radio Frequency Dielectric Heating And Uvc Light [Research Note], Yun Deng, Yuwei Wu, Yuanrong Zheng, Danfeng Wang, Zhenmin Liu
The Philippine Agricultural Scientist
We studied the inactivation kinetics of Cronobacter sakazakii (CS) in infant formula subjected to radio frequency dielectric heating (RF) alone or sequential RF-UVC irradiation for 30 min. We used one linear model and two nonlinear models to fit the data and compared the results. Our findings revealed that CS was more susceptible to the combined treatment than to RF alone at the same temperature and that inactivation rate increased with increasing temperature. The sequential RF (90°C, 5 min) - UVC (25 min) treatment was the most effective at inactivating CS. The survival curves of CS were non-linear. …
