48.00 53.25 Food safety is rapidly changing and[1353] [1219] petfood producers need to proactively protect their operations from potentially dangerous pathogens. The Extru-Tech Advanced Feature Extrusion System features validated pre-kill zones. It’s the only system that provides a Verified Extrusion Process with a Validated Kill-Step at the touch of a button.

In 2016, another trial was conducted at the SyAqua facilities in Bangkok, Thailand, to study the health benefits of the dietary inclusion of a mix of tuna and squid hydrolysates in shrimp (TSH, produced in Thailand).

A total of 1,000 specific pathogen free (SPF) shrimp L. vannamei, of average weight 2g were reared following the usual larval and nursery practices. Following shrimp acclimation to experimental facilities, the trial consisted a 4-week dietary conditioning with experimental diets before the start of a bacterial challenge with Vibrio parahaemolyticus infection and monitoring mortalities for 1 week.
