This work reports on the antimicrobial activity of an ethyl acetate extract of neem ( Azadirachta indica) cake (NCE) against bacteria affecting the quality of retail fresh meat in a broth model meat system. NCE (100 µg) was also tested by the agar disc diffusion method. It inhibited the growth of all tested microorganisms. The NCE growth inhibition zone (IZ) ranged 11.33–22.67 mm while the ciprofloxacin (10 µg) IZ ranged from 23.41–32.67 mm. There was no significant difference ( p ≤ 0.05) between the antimicrobial activity of NCE and ciprofloxacin vs. Jejuni and Leuconostoc spp. The NCE antibacterial activity was moreover determined at lower concentrations (1:10–1:100,000) in micro-assays. The percent growth reduction ranged from 61 ± 2.08–92 ± 3.21. ![]() The higher bacterial growth reduction was obtained at 10 µg concentration of NCE. Species-specific PCR and multiplex PCR with the DNA dye propidium monoazide were used to directly detect viable bacterial cells from experimentally contaminated meat samples. The numbers of bacterial cells never significantly ( p ≤ 0.05) exceeded the inocula concentration used to experimentally contaminate the NCE treated meat. This report represents a screening methodology to evaluate the antimicrobial capability of a herbal extract to preserve meat. Introduction The use of herbal extracts in food preservation is not a novelty and it is increasing, however more herbal extracts need to be tested and validated with alternative methods. Microbial contamination of highly perishable products such as fresh meat is caused mostly by improper livestock rearing and processing practices, unclean processing tools, environments and defective worker hygiene. Furthermore, microbial species which may survive or proliferate on meat after slaughtering and sectioning can be haematogenically spread (diapedesis) from the gastrointestinal system to muscles.

Causes of the spreading are the shocks caused to the animal during the process of culling and transport to the slaughterhouse. Meat contamination results in changes in appearance and odor during prolonged storage. Often Lactic Acid Bacteria (LAB) are responsible of discoloration, slime formation, off-odors and off-flavors as the result of their metabolic activity. However, contamination can also be present without such sensory evidence, requiring deep and adequate controls. The increasing incidence of foodborne diseases, coupled with the resultant social and economic implications, causes a constant impulse to produce safer feed and food and to develop new natural antimicrobial agents [,,]. As a matter of fact, the uncontrolled overuse of antibiotics as common feed supplements could lead to increased numbers of antibiotic-resistant bacteria, and could ultimately compromise treatments of bacterial infections in humans. There is, also, the possibility to transfer the antibiotic-resistant microorganisms into humans both directly via food chain and indirectly by animal waste spread throughout fields. In 1998 the EU health ministers started to ban antibiotics widely used to promote animal growth. In 2006 EU banning regulations in animal feed became effective. In the USA, the food and animal industries have so far successfully blocked most legislation to ban antibiotics in feed. The reality is that most countries underestimate or avoid the problem.
