This study aimed to discover whether Anisakis larvae and residual formaldehyde are present in commercially important fresh marine food animals, Indian mackerel (Rastrelliger kanagurta) and splendid squid (Loligo formosana), obtained from a fish market in Samut Songkhram Province, Thailand. In total, 175 samples of each species were collected in November 2016. Five Anisakis-infected fish were found, accounting for 2.86% of the entire sample, but no infected squid was determined. The most infected internal organ was the ovary, which contained 60.9% (n=14) of the discovered larvae. High formaldehyde contamination was observed in both marine animals using a formaldehyde food-testing kit. These results indicate that seafood, such as fish and squid, should be carefully consumed in Thailand and with appropriate food preparation measures.

Effective trapping of adult mosquitoes in the wild can reduce the spread of deadly human pathogens, such as Plasmodium species causing malaria. The efficacy of this strategy depends on the capacity of the trap to attract and retain insects, and specific odorants such as octenol in mushrooms are strong attractants for mosquitoes. In this study, we assessed the efficiency of a resting box baited with five different extracts from local edible mushrooms, Pleurotus ostreatus, Thaeogyroporus porentosus, Volvariella volvacea, Pleurotus sajorcaju, and Lentinus edodes, for attracting mosquito vectors in Samut Songkhram Province, Thailand. Extracts were used in identical “resting box” at 50, 100, and 200 mg/mL per box. Compared to the unbaited resting box (control), only traps containing 200 mg/mL of L. edodes extract captured significantly more mosquitoes (16.00 ± 3.61 vs. 7.00 ± 1.00 per resting box per night, p<0.05). Attraction efficacy did not increase progressively with tested amount for most extracts. These findings indicate that L. edodes extract can be used as an inexpensive, non-toxic, and locally sourced attractant to increase the efficacy of mosquito control.
