High-temperature tenderizing of beef sides: bacterial considerations

Area of Science:

• Food Microbiology
• Meat Science
• Microbial Safety

Background:

• Beef tenderization is crucial for meat quality.
• Understanding the microbiological impact of novel processing methods is essential for food safety.
• Holding meat at elevated temperatures can influence microbial activity.

Purpose of the Study:

• To evaluate the microbiological effects of an experimental beef tenderizing treatment.
• To determine if the treatment leads to increased bacterial numbers or proliferation of specific microorganisms.
• To assess the safety implications of this tenderization process.

Main Methods:

• Microbiological analysis of beef samples subjected to the experimental treatment.
• Incubation of lean beef sides at 37°C for a specified period postmortem.
• Transfer to a chiller at 3 hours postmortem.
• Quantification of bacterial populations and identification of potential pathogens and spoilage organisms.

Main Results:

• The experimental beef tenderizing treatment did not result in a significant increase in overall bacterial numbers.
• No proliferation of potential foodborne pathogens was observed.
• The treatment did not lead to an increase in food-spoiling organisms.

Conclusions:

• The experimental beef tenderizing method appears to be microbiologically safe.
• This tenderization process does not adversely affect the microbial profile of beef.
• Further research may explore optimization of this method for commercial application.
